Frogs are amphibians, animals that spend part of their lives under water and the remainder on land. They have long, powerful jumping legs and a very short backbone. Most Frogs have teeth (in the upper jaws only) but toads do not have any teeth.

Adult Frogs are characterised by long hind legs, a short body, webbed digits, protruding eyes and the absence of a tail. Most Frogs have a semi-aquatic lifestyle, but move easily on land by jumping or climbing. They typically lay their eggs in puddles, ponds or lakes, and their larvae, called tadpoles, have gills and develop in water. Adult Frogs follow a carnivorous diet, mostly of arthropods, annelids and gastropods. Frogs are most noticeable by their call, which can be widely heard during the night or day, mainly in their mating season.

Life cycle: Like all amphibians, Frogs spend their lives near water because they must return to the water to lay their eggs. Frogs eggs are laid in the water. When they hatch into tadpoles, they breathe with gills and swim using a tail. As they mature, they lose their tail, and they develop lungs for breathing air. In harsh climates, Frogs bury themselves in sand and mud and hibernate (sleep very deeply) through the cold winter.

Diet: Frogs eat insects, catching them with their long, sticky tongue. They also eat small fish and worms.

Classification and Evolution: Kingdom Animalia (animals), Phylum Chordata, Class Amphibia (amphibians), Order Anura (Frogs and toads). The first true Frogs evolved during the early Jurassic period, about 200 million years ago (during the time of the dinosaurs).

The distribution of Frogs ranges from tropic to subarctic regions, but most species are found in tropical rainforests. Consisting of more than 5,000 species described, they are among the most diverse groups of vertebrates. However, populations of certain Frogs species are significantly declining.

Tailed frog
icon1 admin | icon2 types of Frog | icon4 09 11th, 2008| icon3No Comments »

Habitat

The Tailed Frog inhabits clear, rocky, swift, cool streams in forested habitats. In the West this frogs is found primarily in older forest of Douglas Fir, Pine, and Spruce. In the Intermountain Region, the species is found only in Idaho, as far south as Boise, Idaho and as far east as the Salmon National Forest.

While the Tailed Frog never ventures far from water, it can venture into the forest after rains. During dry spells, it can be found on moist stream banks or under rocks in the stream bed. Activities that increase sedimentation and water temperature have an adverse affect on Tailed Frogs. Low dispersal rates limit population recoveries.

Tailed frog

Diet

They eat insects and other invertebrates they catch in the water or on land nearby. They look for food at night. Tadpoles are vegetarians and use their small teeth to scrape algae (AL-jee), or microscopic plantlike organisms, off underwater rocks.

Ecology

Low repro potential: repro maturity age 7-8; 2 yr cycle w/ 1st clutch at age 9 (Daugherty 1982). Extremely philopatric; pro- bably very little gene flow between populations (Daugherty 1982).

Description

This is a small frogs (5 cm total length) that lives in clear, cold mountain streams. It is light to dark brown on the back and usually has slightly granular skin. Adult males are unique among frogs in having a tail-like reproductive organ; females have very small, somewhat tubular cloacal projections.

Appearance

A flat, toadlike frogs with fairly rough skin. Coloring matches the colors of rocks around the stream inhabited - usually olive, brown, gray, or reddish above with yellow and gray mottling, a pale yellow or greenish triangle on the snout and a dark eye stripe. The pupil is vertical. The fingertips are hardened like claws to help the frogs crawl among rocks on stream bottoms. Lungs are reduced to decrease buoyancy, and respiration takes place through the skin.

Toads
icon1 admin | icon2 types of Frog | icon4 08 30th, 2008| icon32 Comments »

Description

American Toads have short legs, stout bodies, and thick skins with noticeable warts. These warts can be colored red and yellow. The warty skin contains many glands that produce a poisonous milky fluid, providing these Toads with excellent protection from many of their predators. This poison is only harmful if it is swallowed or if it gets in the eyes, but it can make many animals very sick.

Anatomy

Toads have poison glands (called parotids) behind their eyes, a chubby body, and shorter legs than frogs. Toads have no teeth, and most Toads have warty skin. The largest Toads are over 8 inches (20 cm) long. Females are larger than males.

Toad

Life cycle

Like all amphibians, Toads must return to the water to lay their eggs. Toads eggs are laid in the water. When they hatch into tadpoles, they breathe with gills and swim using a tail. As they mature, they lose their tail, and they develop lungs for breathing air.

Habitat

Common Toads inhabit damp areas of deciduous woodland, scrub, gardens, parks and fields. In the breeding season, they live in ponds, lakes, ditches and slow-moving rivers.

Diet

Common Toads are opportunistic feeders, catching invertebrates such as insects, larvae, spiders, slugs and worms, on their sticky tongues. Larger Toads also prey on slow worms, small grass snakes and harvest mice, which are swallowed alive. Toads can sometimes be seen in the daytime following rainfall, but they are generally nocturnal, being most active on rainy nights.

Size

A male Toads is around 65 mm in length. The females are around 25mm longer. Sometimes larger Toads can be found, and these are usually females.

Toxicity

All stages of the Cane Toads’s life-cycle are poisonous. The venom produced by the parotoid glands acts principally on the heart. No humans have died in Australia from Cane Toads poison but overseas, people have died after eating Toads and even soup made from boiled Toads eggs. Cane Toads are also poisonous to pets and in Hawaii up to 50 dogs a year have died after mouthing Cane Toads. Signs of poisoning through ingestion include profuse salivation, twitching, vomiting, shallow breathing, and collapse of the hind limbs. Death may occur by cardiac arrest within 15 minutes.

Australian native fauna that have been killed by eating or mouthing Cane Toads include goannas, Freshwater Crocodile, Tiger Snake, Red-bellied Black Snake, Death Adder, Dingo and Western Quoll.

A Cane Toads responds to threat by turning side-on so its parotoid glands are directed towards the attacker. The venom usually oozes out of the glands, but Toads can squirt a fine spray for a short distance if they are handled roughly. The venom is absorbed through mucous membranes such as eyes, mouth and nose, and in humans may cause intense pain, temporary blindness and inflammation.

Description

The Spring Peeper Frog is a small frogs, attaining an adult size between 0.75 and 1.5 inches (up to 40mm) long. They have a dark cross on their backs roughly in the shape of an “X”, though sometimes the marking may be indistinct. The color variations of the Spring Peeper Frog are mostly tan, brown, olive green, and gray. Females are lighter-colored, while males are slightly smaller and usually have dark throats.

Spring Peeper Frog

Diet

Peepers eat small insects, spiders, and worms, catching them with their long, sticky tongue.

Habitat

Found in temporary and permanent ponds, marshes, floodings, and ditches; after the breeding season they move into woodlands, old fields or shrubby areas; common throughout the Great Lakes region, except in the far north along northeastern Lake Superior.

Breeding

Late March into May

Coloring

Brown, tan or gray with dark slanting stripes on the back that usually form an X-shaped mark; the belly is white, yellowish or cream colored; this frogs has some color-changing ability and can darken or lighten, depending on its mood or the surroundings

Aug 23

Description

Red Eyed Tree Frog have bright red eyes and are a really bright color of green with blue and yellow stripped sides. They also have funny looking orange toes. These are definitely one of the more beautiful species of frogs!

Behavior

Bright markings along the sides and on the limbs function to reduce predation. Most of the predators that prey on Agalychnis callidryas often rely on their vision. When the frogs moves to avoid the predator the bright colorations come into view. Because the predator is so locked onto it’s target, when these bright colors flash into view (hence their name, flash colors) they throw off the predator. This is achieved by leaving a ghost image in the visual field of where the frogs was originally. This confuses the predator and gives the frogs time to hide. In other cases, these bright colors often startle the predator and throws them completely off. These flash colors are often well hidden and are only shown when the animal is moving.

Red Eyed Tree Frog

Breeding

Like many tropical frogs, A. callidryas enter breeding mode during the rainy season. At this time, the males will croak incessantly to attract females, and will wrestle other males in the near vicinity. Amplexus consists of the male grasping a gravid female around the abdomen, a position they may maintain for several hours, sometimes days, as the photo at left shows. The male will fertilize the eggs as they are deposited by the female onto top or bottom of leaves. The female chooses leaves hanging above a water source so that when the eggs hatch, the larvae fall directly into the water, where they will continue to develop. The female will deposit several “clutches” during a single breeding session. Between each clutch, she must re-fill her bladder with water, otherwise, the following eggs will desiccate. To do this, she must leave the leaf she is holding onto and enter the water, usually with the male still attached to her back, and then re-attach herself to the leaf again. During this time, it is not uncommon for another male to wrestle the current male off of the females back. The whole breeding cycle is very arduous for both males and females.

In addition to croaking, males are known to “quiver” during the breeding season. This occurs at the peak of a croak, while facing another male. During this staring contest, any sign of movement from one frogs prompts a wrestling match between the males.

Habitat

First identified by herpetologist Edward Cope in the 1860s, the Red Eyed Tree Frog is found in the lowlands and on slopes of Central America and as far north as Mexico. As with other amphibians, Red Eyed Tree Frog start life as tadpoles in temporary or permanent ponds. As adult frogs, they remain dependent on water to keep their skin moist, staying close to water sources such as rivers found in humid lowland rainforests. Red Eyed Tree Frogcan be found clinging to branches, tree trunks and even underneath tree leaves. Adults live in the canopy layer of the rainforest, sometimes hiding inside bromeliads.

Diet

Like may amphibians,Red Eyed Tree Frog are insectivorous. Insects such as crickets, flies, fruit flies, and just about anything smaller than their mouth. Crickets are usually the easiest and most readily available food supply. When feed crickets it is important to gut load the crickets with a good diet to provide the best nutrition for your frogs. Fresh water should be provided in a dish for the frogss because they will rehydrate themselves by soaking in the disk. They will often drink from the water accumulated on the plants from misting as well.

Description

D. auratus frogs reach sizes of about one to 1.5 inches (3 to 4 cm). frogs in some populations may reach 2.5 inches (6 cm). There are many color variants based on geographic area. Most are black and either green or light blue with the black in bands or spots. The stripes or spots can range from blue, blue-green, green, yellow-green, or white.

D. tinctorius is a very large poison frogs. They reach lengths of about two inches (4 to 5 cm). There is quite a bit of variation in size and color. Some can reach 2.5 inches (6 cm).

poison arrow frogs

poison arrow frogs are known for their beautiful colors. These colors are used as warnings to predators that they are poisonous (their poisonous defense evolved to ward off predators.) Some scientists think that the reticulated pattern of the frogs also act as camouflage among the forest shadows. This idea is not the norm.

Behavior

Both sexes defend territories against frogs of the same and other species. Aggressive behavior includes calling and color changes (in males), postural displays, chases, attacks and wrestling (both sexes). Prolonged fights are most likely to occur between frogs of the same sex, but sometimes males and females wrestle.

Poison and Predators

The bright coloration of the poison arrow frogs warns predators that they are poisonous. Once a predator has even licked a poison arrow frogs, it gets very sick and will never try to eat one again. The poison protects them from most predators (except the snake Leimadophis epinephelus, which is immune to the frogs’s poison).

Diet

Poison-arrow frogs have a disadvantage in their feeding habits. They require the tiniest of insects which may sometimes be difficult to procure. They eat ants, termites, small insects, and small spiders.

Habitat

poison arrow frogs live in tropical rainforests of South and Central America.

Lifestyle

These species live in permanently damp leaf litter on the forest floor. They are most active in mornings and evenings.

bullfrogs
icon1 admin | icon2 types of Frog | icon4 08 19th, 2008| icon3No Comments »

Description:Typically, bullfrogs reach up to eight inches in length (measured from snout to vent), but larger specimens occur in some areas. The overall coloration is green or gray brown with brown spots, especially on older specimens. Some brown, yellow, albino and even blue individuals have been observed. Adults have a conspicuous round eardrum, called the tympanum, located on either side of the head. The tympanum is up to twice as large as the eye. A ridge of skin starts behind the eye, runs over the eardrum, and ends at the base of the front legs. There are no lateral ridges on the back. The hind legs are large and powerful and may be banded or blotched with brown. Males have a singular throat pouch that is pale to bright yellow. Females have a white throat. Tadpoles are drab olive green with many tiny black pinhead-sized specks scattered throughout the tail fin and on the back. They may grow up to five inches in length.

bullfrogs

SIZE: Snout to vent length: 9-15 cm (2.5-6 in); record 20 cm (8 in) Legs length: 17-25 cm (7-10 in)

Diet:This is where things get a bit hairy for my taste. These guys have a voracious appetite and will eat anything that it can swallow, including invertebrates and small vertebrates such as mammals, birds, reptiles, fish, even turtles and other frogs. bullfrogs have teeth in the roof of their mouth and a muscular tongue capable of flipping prey into their mouth. They’ll eat lots and lots of really big bugs, fish (guppies, I am told, are pretty good feeders) and mice. Pretty much anything that will fit in their mouths. Large insects and worms should be left on the rocks, though these guys will eat them from the surface of the water too. Dead mice are best offered either by hand or using forceps (again, get the kind with round balls on the ends so you don’t risk injuring the frogs when he lunges at the food!) It is generally recommended that you house these frogs alone (except for breeding) in order to avoid cannibalism. Eeek!

Habitat:These guys are native to the eastern United States, ranging from as far north as Nova Scotia, all the way down to central Florida. They also live as far west as Wisconsin and the Rockies and were introduced widely throughout Colorado, British Columbia, California, and other western states.

They tend to live in vegetation along the edge of large, slow moving, bodies of freshwater.

Where they occur naturally, bullfrogs help keep down the mosquito and insect population. But in some places where they have been introduced, they eat so much that they can destroy local populations of native frogs species!

Their populations can bloom out of control because they don’t really have natural predators (infact, they can give off some nasty toxic secretions from their poison glands (called paratoid glands) that can poison a dog if it tries to eat one!).

Reproduction:Fertilization is external in ranid frogs. In the mating grasp or amplexus, the male rides on top of the female, grasping her with his forelimbs just posterior to her forelimbs. The female bullfrogs deposits her eggs in the water and the male simultaneously releases sperm.

Breeding begins in late spring or early summer. Males defend and call from territories. The call, reminiscent of the roar of a bull hence the frogs’s common name, attracts the female into a territory where mating takes place. A female may produce up to 20,000 eggs in one clutch

Distribution:bullfrogs are perhaps the most widely distributed amphibian in North America. Originally, their range extended from Nova Scotia south to central Florida and west to the Rocky Mountains, but introductions into western lands (for instance, into Utah around the start of the 20th century) have confused the western extent of the original range. Today, bullfrogs are found across most of the lower 48 states as well as in Mexico, Cuba and Jamaica.

Green Tree Frogs
icon1 admin | icon2 types of Frog | icon4 08 12th, 2008| icon3No Comments »

Description

Green Tree Frogs are found in: north Western Australia, Northern Territory, Queensland, northern South Australia, northern New South Wales, in rainforests or in trees or swampy areas.

The Green Tree Frogs is a familiar frogs to many Australians and is the most popular species of pet frogs overseas. They are one of the most widespread amphibians, found in all states except Victoria and Tasmania. They are one of the largest Australian frogs, growing to a size of 12 cm. They have a habit of taking up residence in and around suburban houses, around shower blocks and water tanks, where their call of ‘crawk…crawk….crawk’ can be heard. They sometimes sit beneath outside lights at night to catch insects that are attracted to the light, but they are also capable of taking larger prey on the ground, including mice. They have also been recorded catching bats around cave entrances.

Green Tree Frogs

The Green Tree Frogs population, like many frogs, has also suffered a decline over recent years. The species is long-lived and the oldest recorded captive frogs died at 23 years of age. Because of this longevity the population decline went unnoticed for several years. Adults are still seen and heard regularly but young frogs are becoming scarce.

Appearances

The skin surface of the Green Tree Frogs is smooth with large glands on the back of its head. The glands, if you look closely, are pitted with tiny pores. The fingers and toes have large discs and are webbed. The colour, as the frogs’s name suggests, is usually bright green, however, some individuals may change their colour to olive-brown. Some specimens have white spots on their back, sides and limbs. The back of the thighs varies from yellow to maroon and the iris (the eye) is a pale gold.

The frogs’s skeleton is a bit like ours except that we have five fingers and they have four and they have less ribs than us. They have long bent legs for leaping high, that’s where they get their spring from.

frogs have sticky pads on their feet so they can stick to things. The frogs’s eyes are either red, yellow, brown, green, silver or gold.

Length:

The Green Tree Frogs is 11-14 cm long (stretched out). They can be twice the size of a relative of theirs. They are 4 and a half cm long when they are a tadpole, then they grow legs, drop off their tail and then they leave their home.

Feeding

Small mice, cockroaches, grasshoppers, mealworms, slaters, moths and worms are all suitable foods. Live food is preferred by most frogs, however, you may be able to coax a frogs into taking non-living food by simply wriggling it on the end of a pair of forceps. A varied diet is very important so a culture of some of the above need to be kept. There are excellent reptile supplements available in a powder form, which can be used to dust mealworms to help ensure that your frogs is getting all the correct requirements. Flies are relished by most types of frogs and it can be very entertaining to watch your frogs trying to catch them. They may be purchased from a fishing bait shop as maggots or, alternatively, you can breed your own. About two weeks later, depending on temperature, flies may emerge and crawl through the holes in the lid to be eagerly gobbled up by the waiting frogs. Never use insects that have been killed with insecticide spray.

Feeding response in Green Tree Frogs tends to be stimulated by movement. This can be used to your advantage as particularly fussy frogs can sometimes be persuaded to eat by supplying them with fast moving or flying food. Green Tree Frogs are nocturnal, consequently they are more likely to eat if fed in the late afternoon.

Remember Green Tree Frogs will eat anything that is small enough to fit into their mouth, including other frogs.

It’s best to feed the crickets with calcium-rich gut loading pellets before giving them to your frogs, and you can further ensure good nutrition by sprinkling calcium and multivitamin supplements on the crickets 2-3 times a week.

Habitat

The frogs’s habits are clinging to branches, trees, leaves and twigs. They can also stick to glass. The croaking noise is the frogs’s calling for their mates.

On hot summer days, you can see frogs in the sink, the toilet or the drainpipe.

Fertility

The Green Tree Frogs is an Australian amphibian that can live in water or land. They lay eggs in the water and then they hatch. Some frogs swallow their eggs and then they come out of their mother’s mouth.

In a mixed group of males and females, the males will call loudly during breeding season. In the right environment, females will lay eggs which hatch to become tadpoles.

Life cycle:

The frogs’s life cycle is:

First the mother lays the eggs, then they hatch into tadpoles, after a while they grow legs, after that they lose their tail and then they grow up and they lay eggs.

Banded Bull frog
icon1 admin | icon2 types of Frog | icon4 07 30th, 2008| icon3No Comments »

The Asian Painted Frogs is also known as the Chubby Frogs, the Banded Bull Frog, the Rice Frogs, or the Bubble Frogs. These Frogs have round bodies with mahogany brown backs and cream stomachs. The distinctive stripes down the side can range from copper-brown to salmon pink in color. Males have darker throats than females. Frogs grow to 7-8 cm with females generally being larger than males.

This Frogs is native of South East Asia, and usually lives on the forest floor, in rice fields, and even in populated villages. These Frogs are voracious eaters, and will eat flies, crickets, moths, grasshoppers, earthworms and more. Chubby Frogs hide under leaf litter during the day hours and eat in the evening.

banded bull frog

Chubby Frogs kept in captivity need planted aquariums with plenty of hiding spaces. Since the Chubby Frogs is a terrestrial Frogs, substrate choices should consist of peat/soil mixes or potting soil topped of with sphagnum moss. A water bowl should be included as a water source. Also, the humidity should be kept high by misting the tank a couple times a day with dechlorinated water. Chubby Frogs prefer temperatures of 80 to 85 degrees Fahrenheit. Temperatures may reach 65 degrees at night.

The Banded BullFrog is a highly adaptable species able to survive in disturbed habitats including flooded grassland, roadside puddles and urban storm drains. By day it hides in holes in the ground, under leaf litter or in the crevices of walls or buildings.

The species is easily identified by the thick, black-edged, light brown to orange band which extends from the head along each side of the body. The upperside is dark to medium brown and the underside pale.

The mouth is wide, the head short and blunt and the eyes of moderate size. Generally chubby in form, it will inflate itself when feeling threatened.

Its call is a loud, cattle-like bellow, which can be heard after heavy rain has created flooded pools in which the Frogs assemble.

Chubby Frogs have the ability to expand themselves when threatened, and to secrete toxic glue-like substances from their bodies as a defense mechanism. They are also able to survive dry conditions by burying themselves in the ground and waiting for rain.

Chubby Frogs as pets Chubby Frogs are now commonly sold in pet stores. Those considering chubby Frogs ownership should be aware that like most amphibians, Chubby Frogs cannot tolerate the chlorine found in standard city water. Pets must therefore be provided with treated or spring water. Also, Frogs owners need to consider that Chubby Frogs can be fairly uninteresting as it is quite an inanimate Frogs.

The Banded BullFrog ranges from parts of southern India and Sri Lanka through Burma, Thailand and parts of southern China and Indochina to Peninsular Malaysia, Borneo, Sumatra, Java, Sulawesi and Flores. In Singapore it is considered a highly successful introduced species.
