The Trinket snake is a common non-venomous, terrestrial snake widely distributed in lowlands up to about 600m elevation. It can be found both in forests and anthropological habitats mostly closer to water bodies. It is active during morning hours as well as dusk and considered as a diurnal snake though nocturnal habitats have been observed too. When cornered Trinket snake expands its fore body and open mouth displaying its black color. Hence the vernacular name Katakaluwa (One with a black mouth). It feeds on rodents, frogs and lizards.
