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.

One study found that Cyclopoida made up 67%, Diptera larvae 7.3%, and Heteroptera 6.3% of prey. The skin fragments that were found in their stomach are an indication that these frogs commit cannibalism or eat their own skin which is common among amphibians.
In one experiment, when offered live fruit flies (Drosophila virilis), salamanders chose the larger of 1 vs 2 and 2 vs 3. Frogs can distinguish between low numbers (1 vs 2, 2 vs 3, but not 3 vs 4) and large numbers (3 vs 6, 4 vs 8, but not 4 vs 6) of prey.
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 ...
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 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 ...
The African bullfrog males call out during the rainy season. The call lasts about a second and can be described as a low-pitched whoop. [16] Males have two breeding strategies, depending on their age. Young males congregate in a small area, perhaps only 1–2 m 2 (11–22 sq ft) of shallow water.
Many frogs are able to absorb water and oxygen directly through the skin, especially around the pelvic area, but the permeability of a frog's skin can also result in water loss. Glands located all over the body exude mucus which helps keep the skin moist and reduces evaporation.
