Kinosternon leucostomum
A mud turtle of shallow waters from Central America to north-western South America. It has a black or dark brown carapace, a yellow plastron and hinges that close the shell almost completely.
The white-lipped mud turtle is a kinosternid ranging from south-eastern Mexico through Belize, Guatemala, Honduras, Nicaragua, Costa Rica and Panama to Colombia, Ecuador and northern Peru. It reaches a maximum carapace length of 17.4 cm, and unusually for a mud turtle males grow larger than females, which reach 15.8 cm. The carapace is black or dark brown and usually unpatterned; the yellow to tan plastron has well-developed hinges that close the shell with almost no gap. Two subspecies are recognized: the nominate K. l. leucostomum and the southern K. l. postinguinale from Costa Rica southward, which has a flatter carapace, a narrower plastron and usually clearer head stripes. It lives in shallow, muddy, weedy backwaters of slow lowland rivers, ponds, marshes and ditches and is mainly nocturnal. It is an omnivore taking insects, crustaceans, snails, fish and plant leaves and fruit, and it swallows food underwater. In Japan the nominate subspecies is the more common, with imported animals and captive-bred stock from Japan and Europe available.

Omnivore (insects, crustaceans, snails, fish, plants, fruit)
It lives in shallow, muddy, weedy water and is usually kept in an aqua-terrarium with shallow water it can stand in and a haul-out area.
An omnivore: offer pellets plus fish, crustaceans, insects and greens. It cannot swallow properly on land, so feed it in the water.
It is mainly nocturnal in the wild, though some captives become active by day and bask.
In the dry season it moves overland or rests in damp places. Keep water quality good with regular changes.
The southern subspecies is rarer in the trade and differs in plastron width and head stripes; confirm the subspecies when buying. Never release a captive animal into the wild.
