The caecilians are the third order of amphibians, far less well known than frogs and salamanders. It is viviparous: the embryos develop inside the mother and scrape the walls of the oviduct with specialised foetal teeth.

Fun facts

  • The embryos eat their mother from inside: with special foetal teeth they scrape the inner lining of the oviduct, rich in fat and nutrients, which the mother renews continuously over the seven months of gestation.
  • The caecilians are the third order of amphibians and the least known: some two hundred limbless species, almost all of them underground, that most people do not even know exist.
  • It has a pair of retractable tentacles between the eye and the nostril, chemosensory organs unique to the caecilians with which it detects prey in murky water or underground.
