They are a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds, and mammals ).

The undigested material forms food pellets that are sometimes regurgitated. Most of the chemical digestion and absorption happens in the intestine, while the waste is excreted through the cloaca. Figure 34.4.1 34.4. 1: Bird digestive system: The avian esophagus has a pouch, called a crop, which stores food.Amphibian neuroanatomy was pioneered by studies of the tiger salamander, Ambystoma trigrinum [91]. Since then, correlates of all major vertebrate brain regions found in amniotes have been identified in studies that increasingly use tract-tracing and transcriptomic comparisons (recently summarized in a review reported by González et al. [ 8 ]). ….
