The colourful Emerald Tree Boa, native to northern South America, is mainly nocturnal and spends most of the day
drapped over a branch, often over water. Split into two species in 2009, the Amazonian form with white dorsal stripe
(shown here) is now called the Amazon Basin Emerald Tree Boa (C. batesii) and the other is the Northern.
Both forms have yellow undersides.
Amazonian (C. batesii)
Northern/Guianan (C. caninus)
They can grow to some 6 feet (C. caninus) to 8 feet (C. batesii). They have heat sensors around
the mouth and long teeth to capture and hold warm-blooded prey (mammals/birds/bats) while constricting it to death.
(Juveniles are orange-red.)
