River Cooter

Overview

A large freshwater turtle with a flattened, olive-to-brown shell bearing yellow net-like or 'C' markings, and a yellow plastron. It is strongly aquatic and an excellent swimmer, feeding mainly on aquatic vegetation. Females are noticeably larger than males and may lay eggs on sandbars.

Classification

The River Cooter belongs to the suborder Cryptodira (hidden-neck turtles) and the family Emydidae. It is a largely North American family of mostly semi-aquatic freshwater turtles, including the box turtles that are largely terrestrial. Its scientific name is Pseudemys concinna.

Appearance & Distinguishing Features

They typically have smooth, low-domed or moderately domed shells, webbed feet, and a marked pattern of stripes or blotches; box turtles have a hinged plastron that can close completely.

Habitat & Distribution

They inhabit ponds, lakes, rivers, marshes, and damp woodlands across North America, with a few species in Eurasia. Some box turtles are almost entirely terrestrial.

Diet & Feeding

They are generally omnivorous, eating aquatic plants, insects, fish, amphibians, and carrion, with plant matter increasing in adult box turtles.

Behavior & Conservation

Many bask communally and overwinter by burrowing into mud. The red-eared slider is one of the most widely kept pet turtles, whereas several box turtles are protected owing to declining wild populations.

Popularity & Recognition

The red-eared slider in particular has become the world's most common pet turtle and an invasive species in many regions.
