Eight cantil vipers were born on February 12, the first ever breeding of the species at Denver Zoo. The highly venomous vipers can grow to about two-feet-long and vary in color from brown to black. As juveniles the tips of these snakes' tails are yellowish in color. This serves the sneaky snakes well as they wiggle those tips so they look like worms and lure in small prey.
