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.
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. This is irrespective of other characteristics, i.e. surface area, volume, weight and movement, although discrimination among large numbers may be based on surface area. [169]
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. Based on these results, P. pipa is an ambush predator that will opportunistically eat anything that falls into the water or that it may encounter when occasionally foraging on land.
The northern gastric-brooding frog was a much larger species than the southern gastric-brooding frog. Males reached 50–53 mm (2.0–2.1 in) in length, and females 66–79 mm (2.6–3.1 in) in length.
In 1976, the Southern gastric-brooding frog's population was estimated at 78 individuals in the Booloumba Creek and Conondale Range regions. [4] The Southern gastric-brooding frog suffered from population decline after the winter of 1979. [4] The last recording of the frog in the wild was 1981. [4] In 1983, the last known captive specimen died. [4]
Unlike other frogs, they have no tongue to extend to catch food, so clawed frogs use their hands to grab food and shovel it into their mouths. [13] These frogs are particularly cannibalistic; the stomach contents of feral clawed frogs in California have revealed large amounts of the frog's larvae. [14]
Myobatrachidae, commonly known as Australian ground frogs or Australian water frogs, is a family of frogs found in Australia and New Guinea.Members of this family vary greatly in size, from species less than 1.5 cm (0.59 in) long, to the second-largest frog in Australia, the giant barred frog (Mixophyes iteratus), at 12 cm (4.7 in) in length.
