Spotted something wrong?

It lives buried in the damp soils of the Amazon rainforest, where it hunts earthworms, termites and other invertebrates. Like the other caecilians it has a compact, reinforced skull adapted to digging by pushing with the head.

Fun facts

  • It is one of the largest caecilians in the world and can exceed eighty centimetres, a size that comes as a surprise in an animal almost nobody sees because it spends its life underground.
  • It digs by pushing with its head: its skull is heavily ossified and its jaws close through a muscular system unique among vertebrates, with one muscle working in the opposite direction to the usual.
  • It is viviparous and its embryos scrape the nutritive lining of the mother's oviduct with foetal teeth for months, a layer the mother renews continuously.
