Emerald Tree Boa

Corallus caninus

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The emerald tree boa is an arboreal constrictor of intense green with white lines along the back, which spends the day coiled in symmetrical loops over a horizontal branch with its head in the centre. At night it hunts by ambush: it hangs the front part of its body in a hook shape and strikes at the birds and rodents that pass underneath.

Fun facts

  • biologíaIt lives in the trees of the Amazon, its deep green hiding it almost completely among the leaves; the young are born orange or red before they change colour.
  • Its resting posture is unmistakable: it coils its body into stacked, perfectly symmetrical loops over a branch, with its head resting in the centre, an image that has made this species an icon of nature photography.
  • It senses heat with labial pits so sensitive that it can locate and strike a bird in total darkness, guided only by its thermal signature.
  • Its front teeth are the longest of any non-venomous snake in proportion to the skull, adapted to pierce the dense plumage of birds before gripping them.
