Cottonmouth (Agkistrodon piscivorus)

The Cottonmouth is a semi-aquatic venomous snake often found in marshy bogs or near the river's edge, basking in the sun. 

Moreover, it is a silent predator that is always on the hunt. Its heat-sensing pits between its eyes and nostrils help guide it to its warm-blooded prey, including rodents, birds, and other snakes. 

Male Cottonmouths perform an intricate dance display during the breeding season to attract mates. Moreover, this type of snake is viviparous and gives birth to live young.

In the wild, the Cottonmouth can live up to 15 years; in captivity, this can extend to 24 years.
