About the Bocourt's Water Snake

Subsessor is a genus of snake in the family Homalopsidae. The genus is monotypic, containing the sole species Subsessor bocourti. The species is commonly known as Bocourt's mud snake or Bocourt's water snake and has traditionally been placed in the genus Enhydris.

Both the specific name, bocourti, and the common name, Bocourt's water snake, refer to French zoologist Marie Firmin Bocourt. S. bocourti is found in a wide range of stagnant fresh water habitats in Mainland Southeast Asia. Records from China are questionable.

A robust snake, S. bocourti can surpass 1 m (3.3 ft) in length. S. bocourti is a live bearing species, giving birth to, on average, 3–8 fully formed neonate snakes. S. bocourti feeds on frogs, fishes, and crustaceans. Bocourt's water snake is widely caught for its skin and sometimes also eaten.
