Florida Redbellied Cooter Turtle

The Florida redbelly is closely related to the Peninsula cooter (Pseudemys floridana) and can often be found basking on logs together. The Florida redbelly can be distinguished from the other 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).[2] Females, which average 30.5 cm (12.0 in) in 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.[3][4]
