Identification

Description
This turtle has an olive to brownish carapace, often with faint markings or streaks. The plastron is yellow with dark blotches. One of its key features is a yellow stripe behind the eye that continues down the neck. The skin is dark with yellow striping.

Sexual Dimorphism
Males are smaller and have longer front claws and thicker tails. Females are larger with shorter claws and slimmer tails.

Native Origin and Distribution

Geographical Range
Found in northern Colombia and northwestern Venezuela, mainly in the Magdalena River basin and nearby wetlands.

Preferred Habitat

They live in slow-moving rivers, swamps, marshes, and ponds with soft bottoms and lots of vegetation. These turtles prefer warm, shallow waters and need sunny spots for basking.

Behavior

Feeding Habits
They are omnivores. Juveniles eat more meat—like insects, fish, and carrion—while adults include more plant matter such as aquatic vegetation and fruits.

Predators
Eggs and hatchlings are preyed on by birds, raccoons, and fish. Adults may fall victim to large birds of prey or humans.

Reproduction

Breeding Season
Usually breeds in the dry season when water levels are lower. Nesting follows shortly after mating.

Reproductive Method
Females lay several clutches per year, with each clutch having 5–20 eggs. Eggs are buried in sandy or soft soil near water. Hatchlings emerge after about 60–75 days.

Conservation

Extinction Status
Currently listed as Not Evaluated by the IUCN.

Threats
Major threats include habitat destruction, pollution, and capture for the pet trade or food markets.

Conservation Measures
Some local efforts aim to protect nesting areas. Laws exist in parts of their range to limit commercial collection, though enforcement is weak.

Economic Importance

They are sometimes sold in local pet markets and occasionally used as food. They’re also part of the regional pet trade due to their appearance and similarity to other popular sliders.

Interesting Facts

Trachemys callirostris can live over 20 years in the wild.
They often bask in large groups, sometimes piling on top of each other.
Though similar to the red-eared slider, they lack the red patch and have more yellow striping.
