Most female frogs had around 40 ripe eggs, almost double that of the number of juveniles ever found in the stomach (21–26). This means one of two things, that the female fails to swallow all the eggs or the first few eggs to be swallowed are digested.
The body is similar in appearance to a mottled brown leaf. The feet are broadly webbed with the front toes having small, star-like appendages. Males can grow up to 154 mm long, whereas females can reach up to 171 mm. Females can be distinguished not only by their length but also by their ring-shaped cloacas, visible when they are ready to breed ...
Salamanders, caecilians and some frogs have one or two rows of teeth in both jaws, but some frogs (Rana spp.) lack teeth in the lower jaw, and toads (Bufo spp.) have no teeth. In many amphibians there are also vomerine teeth attached to a facial bone in the roof of the mouth. [143] Edible frog (Pelophylax esculentus) exhibiting cannibalism
The southern gastric-brooding frog was discovered in 1972 and described in 1973, [2] though there is one publication suggesting that the species was discovered in 1914 (from the Blackall Range). [ 3 ] [ 4 ] Rheobatrachus silus was restricted to the Blackall Range and Conondale Ranges in southeast Queensland , north of Brisbane , between ...
Bullfrog stomachs have been found to contain rodents, small lizards and snakes, other frogs and toads, other amphibians, crayfish, other crustaceans, [47] small birds, scorpions, tarantulas and bats, [48] [49] as well as the many types of invertebrates, such as snails, worms and insects, which are the usual food of ranid frogs.

The clawed frog have been kept as pets and research subjects since as early as the 1950s. They are extremely hardy and long lived, having been known to live up to 20 or even 30 years in captivity. [47] African clawed frogs are frequently mislabeled as African dwarf frogs in pet stores. Identifiable differences are: Dwarf frogs have four webbed ...
Since yellow-bellied toads have very specific, typically risky, breeding sites, having a territory is very important since the highest chance of offspring survival occurs ponds that last longer. Not all males can exhibit this wave-generating behavior because it is exclusive to ponds of a specific depth. [10] Note the heart-shaped pupils
Common frog (Rana temporaria) tadpole. A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian.Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial.
