Summary
[edit]DescriptionEmerald Tree Boa (Corallus caninus) (3148920489).jpg | This species has many morphological differences based on locality, enough that some herpetologists have considered whether they should be classified as subspecies. Specimens from the Amazon River basin tend to grow the largest, are much more docile than their Northern relatives and attain lengths of 7-9 feet (210-270 cm), while the overall average size is closer to 6 feet (183 cm). Those from the southern end of their range in Peru tend to be darker in color. Amazon Basin specimens generally have an uninterrupted white dorsal line, whereas the white markings in the Northern Shield specimens are quite variable. The snout scales in Amazon Basin specimens are also much smaller than in their Northern, Southern and Western counterparts found, for example, in Surinam, Venezuela, Bolivia, and French Guiana. |
