Aspect: Very flat red body featuring two dots on its upper surface. The animal is deceptively small. Population: Common. Notable feature: The two darker dots on the rear part of the carapace attempt to replicate a pair of eyes (hence "ocellate"). Rear paddled legs help it swim. Environment: Usually found around rocks and small galleries Behaviour: Particularly visible at night, but will retreat into the first availlable cache if approached too briskly.
