About the Yellow-headed Sideneck

The yellow-spotted Amazon river turtle (Podocnemis unifilis), also known commonly as the yellow-headed sideneck turtle and the yellow-spotted river turtle, and locally as the taricaya, is one of the largest South American river turtles.

Podocnemis unifilis is a type of side-necked turtles, so called because they do not pull their heads directly into their shells, but rather bend their necks sideways to tuck their heads under the rim of their shells. Side-neck turtles are classified as members of the suborder Pleurodira.

Podocnemis unifilis is a large turtle, and can grow up to 45 cm long and weigh up to 8 kg. This species can be recognized by its black or brown oval carapace (upper shell) with distinctive low keels on the second and third scutes. Yellow spots on the side of its head give this species its common name. These spots are most prominent in juveniles and fade with age. Females can be up to twice the size of males.

These turtles are native to South America's Amazon and Orinoco basins, as well as rivers systems of the Guianas. They are found in tributaries and large lakes, naturally calm waters. During the flood... Wikipedia →
