Geographic range[edit]

It is found in Colombia, Venezuela,^[5] Costa Rica, Nicaragua, Panama,^[3] and on the island of Trinidad (in the Republic of Trinidad and Tobago).

Mimicry[edit]

Similar in pattern to a coral snake,^[4] this species probably gains protection through mimicry.

Diet[edit]

It feeds mainly on other snakes.^[4]

Habitat[edit]

It is a forest dweller,^[4] often found in the leaf litter or burrowed in the soil in rain forests.

Symbiotic relationship[edit]

It burrows primarily near the Pouteria caimito, commonly known as the abiu, a tropical fruit tree, the nutrients of which supply the snake's clutch of eggs. In turn the tree is fertilized by the snake's urine and embryotic fluid.
