Fun facts

  • GeneralIts molar-like teeth are specialised for crushing water snails.
  • It eats almost nothing but snails: it has broad, flattened molars and enormous jaw muscles for crushing the shells, and then spits out the fragments and swallows only the flesh.
  • Its specialisation is so extreme that its skull resembles that of a durophagous mammal more than that of a lizard, and it is a classic case study in the functional anatomy of reptiles.
  • It swims with its laterally flattened tail, like a crocodile, and can stay submerged for long stretches searching for snails on the floor of flooded forest.
