Hence it is, by definition, venomous. Notice that the head is also narrow. A slender, moderately long snake, the North American Racer ranges from 20 to 65 inches in length. This Brown Watersnake has a slender body and has a relatively long, thin tail.

The Cuban Racer is harmless to humans but does kill its prey through neuroparalytic venom. There are no land dwelling snakes in Cuba that pose a risk to humans. Considered one of the rarest and most endangered snake species in the world; only 60-80 adults believed to remain. I always find these discussions interesting. In adults, color of the back can vary from uniform greenish gray to brown or blue. LONG, SLENDER BODIES: Non-venomous watersnakes (and other harmless snakes) have bodies that are more slender for their length, and longer tails. The belly is whitish to pale yellow, the latter extending onto scales of the upper lips and nasal region of the head. Antiguan racer: Critically endangered. The Cuban boa is the largest species in its genus as well as the largest snake inhabiting the West Indies; in fact, it's the largest vertebrate in the West Indies as they can be over 15 feet long. For food, they tend to eat other prominent vertebrate, including the Cuban rock iguanas and the hutias. Endemic; found only on Great Bird Island off the coast of Antigua.
