Varuna yui
Family Grapsidae

Size:
up to 5 cm, continental Southeast and East Asia

The paddlers are common in back mangroves and at the edges, especially near areas where freshwater streams flow in. These crabs are effectively freshwater crabs, but adults must return to the sea to hatch their eggs. They are scavengers. In many Southeast Asian countries, these crabs are collected for food, and the females with eggs (gravid) are especially sought after.
