Mangrove snapping prawns
Alpheus spp.
Family Alpheidae


Two species are common locally, the Banded mangrove snapping prawn (A. euphrosyne, 2-3 cm) and the Giant mangrove snapping prawn (A. microrhynchus, up to 8 cm).

They are rarely seen but can be heard snapping away when they are disturbed.

Alpheus euphrosyne is the more common species, digging burrows under logs and roots.

They snap using their enlarged claw which has a special tooth on one finger which fits into a depression on the other finger. The tooth hits the depression with so much force that it resonates. This is strong enough to ward off competitors, predators as well as stun prey. Snapping shrimp are opportunistic feeders.
