Big-headed Amazon river turtle  (Peltocephalus dumeriliana)

The big-headed Amazon river turtle is an omnivorous species that feeds on fish, invertebrates, fruits and seeds, aquatic plants and algae. Hatchlings reportedly feed on fish and vegetable matter (2).

In Colombia, this turtle nests during the dry season, starting in mid-December and, in Brazil, hatching has been observed in August and September (2). Clutches contain seven to 25 eggs, which are incubated in a flask-shaped nest 12 to 24 cm deep in floodplain forests for at least 100 days (2) (4).
