Some palaeontologists prefer to use the name Apoda to refer to the "crown group", that is, the group containing all modern caecilians and extinct members of these modern lineages and the name Gymnophiona to refer to the total group, that is, all caecilians and caecilian-like amphibians that are more closely related to modern groups than to ...
On land, amphibians are restricted to moist habitats because of the need to keep their skin damp. [31] Modern amphibians have a simplified anatomy compared to their ancestors due to paedomorphosis, caused by two evolutionary trends: miniaturization and an unusually large genome, which result in a slower growth and development rate compared to ...
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 male remains in the brood site awaiting a female. When a female approaches, the male guides or drives her into his burrow and prevents her from leaving until she oviposits. [15] Female hellbenders lay 150–200 eggs over a two- to three-day period; the eggs are 18–20 mm (0.71–0.79 in) in diameter, connected by five to ten cords.
Once ready, the female deposits the eggs in a safe location, usually on the underside of a rock or log. [7] They can lay from 20 to 200 eggs, [4] usually an average of 60. [6] The eggs are not pigmented and are about 5–6 mm (0.20–0.24 in) mm in diameter. The female stays with her eggs during the incubation period (around 40 days).
The average mass is 22.7 g (0.80 oz); the female is usually slightly larger than the male.

Amphisbaenia / æ m f ɪ s ˈ b iː n i ə / (called amphisbaenians or worm lizards) is a group of typically legless lizards, [2] comprising over 200 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes.
