Rhynchophis boulengeri

The sharp-beaked snake, whose Latin name is Rhynchophis boulengeri, is a small snake of the family Colubridae.

The sharp-beaked snake is a tree-dwelling non-venomous snake. Like other tree-dwelling snakes such as the green snake, it lives in trees all year round and feeds on some lizards, insects, and small birds. It was first named in 1897, and its origin is located in Vietnam.

The breeding period of the sharp-beaked snake is the same as most snakes in China. It mates from March to May, lays eggs at the end of June, and hatches for one to two months. The output is small, usually 3 to 10 snake eggs. The young snakes have a color development process (the body color of the young and the adult is different, and the body color gradually tends to the adult body color as they grow older).

It is included in the "List of Terrestrial Wildlife with Important Economic and Scientific Research Value under State Protection" issued by the State Forestry Administration of China on August 1, 2000.

It is included in the second level of the "List of National Key Protected Wildlife in China".
