Brief SummaryRead full entry
BiologyCagle's map turtle is a diurnal species that spends much of the day basking on logs and rocks in the water. A predominantly aquatic species, this turtle rarely comes onto land other than to nest (8). Hatchlings have been collected from September through November, indicating that the nesting season likely occurs in late spring to early summer (2). As many as three clutches of one to six eggs may be laid by a single female each year, deposited in nest-cavities approximately 15 centimetres deep near the water (2) (8). Sex is temperature-dependent, with lower nest temperatures producing males and higher temperatures producing females (8). Female Cagle's map turtle feed almost exclusively on Asian clams, while the males predominantly consume caddisfly larvae, and occasionally other insects and small molluscs (9). This difference in diet is correlated to the difference in head-width between the sexes (6). Plant remains have also been found in specimen's stomachs, but are thought to have been ingested incidentally (2) (8).
