Description

Dendrophidion percarinatum is a forest snake that lives on the forest floor. Its size varies from 40.1 to 85.2 cm (15.8 to 33.5 in). [3] It has 147 to 170 ventral scales, 84 to 106 dorsal scales, [3] and 133 to 164 subcaudal scales. [4] One main characteristic is the presence of a divided anal plate. [5] Its coloration is dark brown or gray dorsally, with a lighter, cream color on its underbelly. Additionally, on its dorsal side, it has black cross bars with light dots that cover most of the snake's body. [5]

Geographic distribution

Dendrophidion percarinatum is found in Honduras, Nicaragua, Costa Rica, Panama, northern Colombia and northwestern Venezuela, [2] with the population in Venezuela believed to be a distinct population from the rest of the range. [3] [6] It is normally found at elevations <1000 m but has been found up to 1200 m in southwestern Costa Rica. [3]

Behavior

Dendrophidion percarinatum is a diurnal and semi-arboreal snake that primarily consumes frogs, lizards, and other small animals that live in the leaf litter present on the forest floor. [3]

Reproduction

Dendrophidion percarinatum is oviparous, and has an average clutch size of 3 to 6 eggs. [3] [7]
