Alpheus sulcatus Kingsley, 1878
Alpheus sulcatus is a free-living, rather large snapping shrimp that lives under rocks and among coral in the eastern Pacific. A. sulcatusbelongs to the Sulcatus species group within the genus Alpheus (Kim and Abele 1988). Although this species has also been reported in south Africa, Australia, and the Red Sea, it is likely a species complex (Knowlton et al. 2008, Anker et al. in prep); see http://biogeodb.stri.si.edu/bioinformatics/alpheus/Alpheus_Template.php?... for more details.
