Decapoda - Brachyura - Ocypodidae - Uca

Uca major (Herbst, 1782)

World Distribution
Crane (1975: 136) - Tropical western Atlantic, known with certainty from the West Indies, Panama, Venezuela, and French Guiana. Reported once from Mexico (Kingsley, 1880.1), but no material has been found and the record should probably be considered questionable. Occurrence in Brezil (Seba, 1758 and 1761) also unproved (see under type material). The range in the West Indies consists of the following localities: Chace & Hobbs (1969) listed the Bahamas (Bimini, San Salvador), Cuba, Jamaica, Puerto Rico, Saint Croix, and Guadeloupe; von Hagen (1970) added Haiti, on the basis of specimens he found in the Hamburg Museum, and Trinidad, where I also found the species to be present but rare

Environnement : Marine & Land - Substrat/Association : Soft bottom (mud or sand)

Comment(s) on data
During Karubenthos 2012, U. vocator was found with U. rapax in mangroves, but not U. major as indicated by Desbonne (as G. grangeri). According to Crane (1975: 629, key) the front is narrow in this species but wide in U. vocator.
