Keelback and Olive Keelback

Most of the 20 or more kinds of watersnakes in India are
"keelbacks"-which means that each scale has a tiny fold in it. The most common freshwater snakes are the checkered keelback and the olive keel back. Both are widely found in India but are mostly snakes of the plains and lower hills. The checkered keelback varies in color from back to yellow, with a back-and –white checked pattern. It has black straks on the eye and a long head. It is active both during day and at night. We have seen them flatten their head
seasnake2s and rear up like cobras when frightened. A freshly caught checkered keelback is a real biter. 

The female lays her 20 to 40 eggs in a hole or tunnel, and stays with them until hatching time.


The olive keelback has a thinner head than its checkered cousin, and its body is dark green. It is a cool-headed snake which almost never bites (unless you are a tadpole or frog!). one of the most interesting thing we know about olive keelback is that it eats mosquito larvae; another friendly service that snakes of free of cost!
