A Surinam Coralsnake (Micrurus surinamensis) in Amazonian Peru.
The Surinam Coralsnake, Micrurus surinamensis, spends a lot of time in the water chasing fish. The snake’s potent venom subdues fish, which it eats quickly. But the toxicity of the venom makes this species exceptionally dangerous to humans. Bites are extremely uncommon owing to the low incidence of human-snake interaction. This individual was photographed on the Rio Samiria, Loreto, Peru, November 2013.

The Aquatic Coral Snake is of the largest and stoutest of all coral snakes, with adults usually 0.8 to 1.0 m long. They swim very well and can remain submerged for extended periods.
