Claudius angustatus
A turtle with a tiny plastron that looks like a bib, which inspired its Japanese name. It has a large head, a sharp beak and three keels along the carapace, and is the only living species of its genus.
The narrow-bridged musk turtle is a kinosternid in the subfamily Staurotypinae found at low elevations in Mexico (central Veracruz, northern Oaxaca, Chiapas and Tabasco), northern Guatemala and Belize. As of 2010 it is the only living species of Claudius. Maximum carapace length is about 18 cm, and males are larger than females, which reach about 15 cm. The elongated oval carapace has three longitudinal keels that fade with age. It is brown to tan with wood-grain lines and sometimes bright yellow edging, but older animals are often covered with algae that hide the pattern. The English name refers to the narrow bridge between carapace and plastron, which is joined by ligament rather than scutes, and the Japanese name refers to the very small, bib-like plastron. The head is large and bulbous with a sharp beak and a long neck. It is almost entirely aquatic, walking along the bottom of slow creeks and weedy shallow ponds to forage for aquatic insects, other invertebrates and carrion. In Japan it is only occasionally seen in specialist shops.

Mainly carnivorous (aquatic invertebrates, carrion)
Almost fully aquatic and walks along the bottom rather than swimming. Use a fairly shallow, planted tank with a haul-out area.
Wild animals eat aquatic insects, other invertebrates and carrion; in captivity combine pellets with shrimp, snails, small fish and insects.
With its large head and sharp beak it can bite, so hold it by the rear of the shell.
It can release foul-smelling musk from glands under the shell, and older animals readily grow algae on the shell.
Unlike most turtles, sex is thought to be determined genetically rather than by incubation temperature. Never release a captive animal into the wild.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Narrow-bridged Musk Turtle is up to about 16 years (captive record). With proper care and nutrition, they can live a long and healthy life.
Narrow-bridged Musk Turtle typically reaches Maximum carapace length about 18 cm (females up to about 15 cm) as an adult. Size may vary depending on care conditions and individual genetics.
