A fine specimen of Ebony Keelback (Chironius grandisquamis). This genus of snake is aptly named for a rigid "keel" that runs the length of their spine. This individual was found in the northern Caribbean foothills of Costa Rica. Specimens from the southern pacific part of the country exhibit a blue-ish coloration, darker tongue, and a completely creme colored venter. With genetic testing, they may prove to be a separate species all together.
