Geograpsus lividus

Zoeae G. lividus found in the Atlantic possess more outer minute spines on the furcal arms of the telson as well as more aesthetase setae, bristles, on the antennule.

[8] Geograpsus lividus is native to east Africa, the Cook Islands, Hawaii, and the western Atlantic.

[8][10] They are considered a supratidal species as they tend to occupy the upper region of the intertidal, residing in sediments deposited by extreme tides.

[12] While the specific diet of G. lividus has not yet been investigated, other members of the Geograpsus genus including G. grayi and G. crinipes are carnivorous.

[13] They are able to tear through shell as well as softer substances using flattened lateral teeth and a rounded medial tooth in the center of their mouth.

[12] Geograpsus lividus utilizes indirect sperm transfer; some form of precopulatory mating ritual has also been observed.
