Fun facts

  • GeneralIt buries itself in the sand with only its eyes showing, to ambush rodents.
  • It lives virtually buried: its wedge-shaped snout works like a spade and its tiny, upward-facing eyes let it watch the surface while the rest of its body stays under the sand.
  • When it feels threatened it tucks its head under its body and raises its tail, offering the predator a blunt, expendable end instead of its head.
  • It is one of the longest-lived boas in captivity for its size: there are individuals that have passed thirty years while weighing less than a kilo.
