Pyxis arachnoides
Pale brown or yellow rays radiate across the black carapace and resemble a spider web, hence its English and Japanese names. It is small, with a carapace to 15 cm, and most animals have a hinge on the front lobe of the plastron.
Pyxis arachnoides is endemic to southern Madagascar and, although the largest of its genus, is small, with a carapace to 15 cm. The shell is domed and elongated seen from above. Vertebral and costal scutes are black with pale brown or yellow rays - six to eight on the vertebrals and four to six on the costals - which resemble a spider web and give the tortoise its English and Japanese names. The marginals are yellow with black markings. A hinge between the abdominal and pectoral scutes lets most animals move the front lobe of the plastron, though one subspecies lacks it. It lives in coastal grassland, forest and scrub, is active in the rains and just after them, and rests through the dry season under leaf litter and fallen wood. It is herbivorous, eating leaves, fruit and mushrooms. Collection for the pet trade and predation of eggs and juveniles by introduced bush pigs have caused a steep decline.

Humidity

Leaves, fruit, mushrooms and leafy greens
Provide a basking site of 29-32 C at one end of the enclosure and let the other end run cooler to create a gradient. It is important to keep humidity adequate without soaking the enclosure; a patch of dampened sphagnum moss is one way to do this.
It burrows seasonally, so use a deep substrate of 15-20 cm; a mix of cypress mulch and topsoil works well for digging. An enclosure of about 60 by 90 cm and 30 cm high suits one adult. Add hides such as half flowerpots and a shallow water dish.
Herbivorous, eating leaves, fruit and mushrooms. In captivity, base the diet on leafy greens.
Small and placid. It rests under leaf litter and fallen wood through the dry season, and captive animals likewise spend periods buried out of sight.
