Snap Jaw, Gaper - Cottonmouth

The world's only aquatic pit-vipers has a lot of names and a bad reputation. This video explains how Cottonmouths bite once, let go, and then tracks its prey down. Sometimes, they wait for a pond to dry so they can get easy access to fish that cannot get away. Unlike many common snakes such as racers and Rat snakes, Cottonmouth snakes will hold their ground when threatened. The video also explains why paved roads are attractors to Cottonmouths and Coppeheads. It simply is good basking spots for the snakes.

Cottonmouth in HD

The Latin name of Cottonmouth - Agkistrodon piscivorus leucostoma already tells that this snake is white inside its mouth. It is the leucostoma name that does that. The video is shot in Texas where Cottonmouths are common. Look at the facial stripes behind its eyes. That is very characteristic for Cottonmouths. Another characteristic is that their entire bdoy is high in the water when they are swimming. The circle at the bottom of its mouth is a breathing tube so it can breathe while swallowing. Heat seaking pits are just below the eyes.

Cottonmouth - from Alabama

The Cottonmouth opens its mouth as soon as the guy stands up or get closer. It's easy to see its triangular shaped head in this video. Some of the myths associated with the snake is that they chase people, which is of course not true. They actually rattle with their snake a little bit and it makes a silent rattle. As he mentions, do not corner it.
