.Description
The elephant trunk snake possesses a wide and flat head, and its
The skin is baggy and loose
The top of the head has no large shields, but instead is covered with very small granular scales. There are no ventral scales. The body scales are in about 120 rows around the body. The body is stout, and the tail is short and prehensile.[4]
The elephant trunk snake is fully adapted to live underwater so much that its body cannot support its weight out of water and leaving the water can cause it serious injury.[citation needed]
Reproduction
An aquatic snake, the elephant trunk snake is ovoviviparous, with the incubation lasting 5 to 6 months and the female expelling 6 to 17 young.[1]
Geographic range
The elephant trunk snake is found in
Habitat
The elephant trunk snake has a coastal living habitat like rivers, estuaries and lagoons. But it prefers freshwater and brackish environments.[2]
Feeding
The elephant trunk snake is an ambush predator that preys on fishes and amphibians. It usually catches its prey by folding its body firmly around the prey. Its loose, baggy skin and its sharp scales find their utility by limiting any risk of escape of the prey, in particular fishes which have bodies covered with a viscous, protective mucus.[2]
Behaviour
The elephant trunk snake is nocturnal. It spends most of its life under water and rarely goes on land. It can stay under water for up to 40 minutes.[2]
