The Florida red-bellied cooter or Florida redbelly turtle (Pseudemys nelsoni) is a species of turtle in the family Emydidae.

Etymology

The specific name, nelsoni, is in honor of American biologist George Nelson (born 1873).[3]

Geographic range

P. nelsoni is endemic to Florida, and southern Georgia.

Biology

The Florida redbelly cooter is mainly herbivorous, and can be found in nearly any type of aquatic habitat. It reaches particularly high densities in spring runs, and occasionally can be found in brackish water. This species is active year-round and spends a large portion of the day basking on logs. They are noted for sometimes laying their eggs in the nest mounds of alligators. The Florida redbelly is closely related to the Peninsula cooter (Pseudemys floridana) and can often be found basking on logs together.

Description

The Florida redbelly can be distinguished from other similar turtles by its distinctive red-tinged plastron (belly) and two cusps (like teeth) on its upper beak. Like most Pseudemys turtles, this species is a fairly large river turtle. Carapace length in mature turtles can range from 20.3 to 37.5 cm (8.0 to 14.8 in).[4] Females, which average 30.5 cm (12.0 in) in carapace length and weigh 4 kg (8.8 lb), are noticeably larger than males, which are around 25 cm (9.8 in) and 1.8 kg (4.0 lb) in mass.[5][6]

Export

Florida redbellies are commonly exported for consumption and the pet trade, with about 50% wild caught individuals and 50% captive bred.

Most of US export statistics (as collected by the World Chelonian Trust in 2002-2005) simply describe exported turtles by the genus, Pseudemys, without identifying the species. They are exported by the million, and are mostly farm-raised.[7]
