Heosemys spinosa
The sharp spines on the marginal scutes of juveniles give the turtle its English and Japanese names, and the specific name spinosa means spiny. The spines disappear with growth. It is the smallest member of its genus, with a carapace to 22.5 cm.
Heosemys spinosa is the type species of its genus and the smallest member of it, with a carapace of 18-22.5 cm. The shell is rather flat and a broad barrel shape seen from above, brown with paler yellowish brown along the keel. The plastron is yellow to yellowish brown with radiating black markings. Its most striking feature is the shape of the juvenile: the marginal scutes end in sharp points and further spines run along the rear of the keel, the costal scutes and the front of the gular scutes. The specific name spinosa, meaning spiny, matches the English and Japanese names, and the spines are thought to deter predators. They are lost with growth and the carapace darkens. In adult females the joint between the rear of the carapace and plastron becomes ligamentous, giving the plastron some movement and making it easier to lay large eggs. Terrestrial, it lives around forest streams below 900 m and rests buried in leaf litter.

As a tropical species it suffers in the cold, but it also does badly in heat: many individuals become inactive or go off food when the air is too warm. It dries out easily, so keep moisture in the substrate. One captive clutch hatched after 106 days at 26-30 C.
Keep it in a terrarium. It likes to burrow, so use a moisture-retaining substrate such as leaf mould or coconut husk, deep enough to bury the shell. Provide a water dish the turtle can sit in, filled to about half the height of the shell, and keep it clean because the turtle often defecates in the water.
It is considered herbivorous, so feed mainly chopped vegetables and fruit; some captive animals take prepared pellets. Juveniles are more omnivorous, but a diet heavy in animal food can cause developmental problems and sudden death.
Being a forest animal it appears to dislike very bright lamps. Use UV lighting indoors but position it so the light is not glaring. It is placid and shows little aggression towards other animals.
Listed on CITES Appendix II with effect from 13 February 2003; Appendix II species need no individual registration certificate in Japan, and this one is neither a designated dangerous animal nor an invasive alien species. Thailand and Myanmar protect it by law and ban commercial export, and Singapore and the Philippines restrict export tightly.
