Common Trinket Snake

The Common Trinket Snake is a non-venomous snake that has aroused curiosity and fear through many myths. We believe that this snake got the name ‘Katakaluwa’ because of the black color inside its mouth. The biggest myth about Common Trinket Snake is that they are formed by combining a Cobra and a Common Rat Snake.


Snakes of two different thicknesses never reproduce, and Coelognathus snakes, which belong to the genus Coca, are widespread in other parts of Asia except ours. The myth is believed to have been formed because the Common Trinket Snake grows to about 130cm and has white spots on the anterior part of the body and only two brown lines running bilaterally without any transverse band on the posterior region.
