Madagascar big-headed turtle

By

This critically endangered freshwater turtle was long thought to be in the otherwise South American genus Podocmemis, which includes the Arrau and Yellow-spotted side-necked turtles, also displayed at the DWA. More recent research indicates it belongs in its own genus, but that its closest living relatives are South American, evidence of Madagascar and South America both being part of the Gondwana Super-Continent until it split apart approximately 135 million years ago. Efforts are underway to establish a captive-breeding program.

Yellow-spotted Amazon turtle

In the 1960s, vast numbers of the tiny, brightly colored young of this species were sent to the US with shipments of tropical fish, but most did not survive. Since females may exceed 17 inches in shell length, they are not appropriate for most home aquariums. Serious private collectors and zoos have done well with them, and they have bred many times in captivity. While considered vulnerable to extinction, they remain an important resource for Native Americans in parts of their wide South American range.
