Calamaria Reed Snake

The calamaria reed snake is a small snake found in parts of South Asia, including Sri Lanka, Bangladesh and the Western Ghats of India. It is light brown, greyish-brown or greenish above, with the scales usually edged in black to form fine longitudinal lines, the most conspicuous being one on each side of the spine. The underside is whitish, yellow in life, and a series of dark spots on each side of the head are the remains of temporal stripes (Wikipedia, general species account).

The head is not flattened and is fairly distinct from the neck. Quoted measurements give a male total length of 335 mm and a female of 390 mm. Nationally Near Threatened (Sri Lanka National Red List 2012).
