  Pebble crabs
Family Leucosiidae

0.5-0.8 cm

Pebble crabs are rare in mangroves, but two species are only found here.

The more common is the small Millet crab (Ebalia malefactrix), while the larger and much stouter Cheryl crab (Praosia punctata) was only formally described from Singapore in 1993.

They hide in small pools or along stream banks. They are slow-moving and hide under soft mud during the day. As such, they are rarely seen. Like most leucosiids, they feed on small animals in the muds.
