About Gelasimus vocans (Linnaeus, 1758)
Gelasimus vocans is a species of fiddler crab. Its distribution spans the Indo-Pacific region, ranging from the Red Sea, Zanzibar, and Madagascar to Indonesia and the central Pacific Ocean. This crab lives in burrows that can reach up to 50 centimetres (20 inches) deep. Multiple different forms of Gelasimus vocans have been identified, and the researchers who described these forms have often classified them as either full species or subspecies. Gelasimus vocans was formerly classified under the genus Uca; in 2016, it was moved to the genus Gelasimus, which was previously a subgenus of Uca.
