Conservation

IUCN Red List status is Least Concern. Common and widespread throughout its natural range, though local populations face threats from habitat loss and intentional killing.

Physical Description

Features a heavy-bodied build with keeled scales. The coloration consists of dark reddish-brown, brown, or black crossbands or blotches over a lighter yellowish, tan, or reddish-brown background. The belly is typically patterned with dark markings. The head is distinct from the neck.

Size & Dimensions

This individual appears to be a juvenile measuring around 10 to 15 inches. Adults typically range from 24 to 42 inches (60 to 106 cm) in total length, with maximum lengths exceeding 50 inches.

Habitat

Found primarily in and near freshwater habitats such as streams, rivers, swamps, marshes, ponds, and lakes. Highly aquatic, spending much time in the water or basking on overhanging branches and banks.

Diet & Feeding

Feeds primarily on fish, amphibians (frogs and toads), and occasionally crayfish or other aquatic prey. Utilizes an active foraging strategy in water, capturing prey with the jaws and swallowing it alive.

Reproduction

Viviparous (gives live birth). Mating typically occurs in spring, with litters of 10 to 50+ young born in late summer or early autumn.

Conservation Status

IUCN Red List status is Least Concern. Common and widespread throughout its natural range, though local populations face threats from habitat loss and intentional killing.

Cultural Significance

Plays an important ecological role in controlling populations of fish and amphibians in freshwater ecosystems. Frequently misunderstood and misidentified, leading to unnecessary persecution.

Notable Features

Exhibits strong aquatic adaptations, including nostrils and eyes positioned high on the head to allow breathing and viewing while mostly submerged.
