|Button crabs Phlyra punctata
These little crabs (carapace diameter up to 2 cm) are often found on night dives on sandy areas. As I have rarely seen them during the day I would assume that they remain burried then. Although the dorsal surface of the carapace seems smooth, it is actually covered by numerous small pits, although in young individuals the surface may actually be granulate, with small raised bumps. They are found from Saldanha to Port Elizabeth.
