GALLERY
IMPORTANT: Many snakes have significant variance in coloration and pattern even within the same species. There can also be extreme differences in appearance from juveniles to adults so it is important to never assume you have properly identified a snake.
DESCRIPTION
Wide range of coloration including tan body with grayish brown patterns and coloration, sometimes light tan in color but can also be red, bright orange, yellow or almost entirely black. Head usually displays a V pattern. Large eyes with roundish oblong pupils. Mock Vipers are largely terrestrial and have thin necks relative to their head, which is somewhat V shaped. Head can flatten slightly when defensive appearing similar to vipers. Faint white and tan spots on the body also can display orange speckles on upper third of the body on the lower sides, sometimes displaying lateral banding in light brown from mid to lower body extending to the tail. As a front fanged snake they are mildly venomous but there are no known cases of serious envenomation or reactions in humans. Also, they frequently referred to as ‘rear fanged’, a label that can be somewhat misleading as the fangs are located more towards the first third of the mouth.
BEHAVIOR
The Mock Viper is a daytime active, largely terrestrial snake and as such can often be found in leaf litter, though they are known to also climb small bushes and vegetation especially over watered areas where they have been observed to eat small frogs. They also commonly display defensive behavior by positioning their front half into an 'S' position. They will strike mostly with false bites and occasionally real hits, but their diminutive size renders any genuine bite relatively harmless.

HABITAT
Due to their tendency to hide in leaf litter Mock Vipers are generally found in forested areas, often close to some water source. They have also been observed hanging from branches over water possibly hunting for fish or amphibians.
MISTAKEN IDENTITY
NO SNAKE SHOULD EVER BE HANDLED BY ANYONE BUT EXPERTS: The Mock Viper as its name indicates can appear in general like a viper species. It is possible to be confused with juvenile Mountain Pit Vipers or Pointed Scale Vipers and as a result Mock Vipers should be observed at a distance and never handled.
