Geograpsus lividus is found in the Western Atlantic and Eastern Pacific. In the Western Atlantic: Bermudas , Florida Keys, Gulf of Mexico, New Providence Island, Cuba , Jamaica , Puerto Rico , Isla de Vieques , St. Thomas, St. Croix, St. Martin , Saba, Guadeloupe, Isla de Aves, Dominica , Martinique, St. Lucia , Barbados , Trinidad , Margarita, Isla de Cubagua, Tortuga , Los Roques, Bonaire , Curaçao , Isla de Providencia, Colombia , Venezuela , and Brazil . In the Eastern Atlantic: from Senegal to northern Angola and Cape Verde . In the Eastern Pacific: Baja California to Chile , and Hawaii ( Rathbun 1918 ; Chace & Hobbs 1969 ; Melo 1996 ; Poupin 2018 ). Distribution in Barbados . Cattlewash, St. Peter’s Bay, and Sherman’s [ Table 1 (Site #s: 5, 24 & 26)]. Habitat in Barbados . Rocky shore under debris and fragmented coral rocks (diameter size: 4–20 cm ), and cobble rocks (diameter size: 10–50 cm ) in supralittoral zones ( Fig. 2A : C, D). Ecological notes. Specimens of Geograpsus lividus were collected in the same habitat as Cyclograpsus integer during the daytime. The crab can be often seen scurrying to seek shelter under the same rock/cobble or pile of debris as Cyclograpsus integer . Remarks. The Barbados-Antigua Expedition (1918), collected one female from Pelican Island, Barbados . This specimen is stored at USNM (Catalogue # 75247). According to Rathbun (1921) , this species is nocturnal; however, Geograpsus lividus was collected during the day in the present study. Pelican Island no longer exists in Barbados as it was incorporated into the Deep-Water Harbor complex in 1961. Additionally, one (1) male specimen was deposited at the USNM (Catalogue # 76563) by G.S. Miller; this specimen was collected from Barbados in 1924.
