Ocypode brevicornis

''Ocypode brevicornis'' is a species of ghost crabs native to the Indian Ocean, from the Gulf of Oman to the Nicobar Islands. They are relatively large ghost crabs with a somewhat trapezoidal body. The carapace reaches a length of and a width of . They are a mottled brown to yellow in coloration. Like other ghost crabs, one of their claws is much larger than the other. Their eyestalks are large and elongated, tipped with prolongations at the tip known as styles. They are common inhabitants of open sandy beaches, living in burrows in the intertidal zone.
==Taxonomy==
''Ocypode brevicornis'' was first described by the French zoologist Henri Milne-Edwards in 1837. However, his type specimens consisted only of two juvenile individuals from Pondicherry, India. In 1852, he again described the same species from adult specimens recovered from the same area as ''Ocypode platytarsis''. In 1880, the American zoologist John Sterling Kingsley synonymized ''Ocypode brevicornis'' with ''Ocypode ceratophthalma''. As a result, only ''Ocypode platytarsis'' was regarded as valid for the entirety of the 20th century. And most literature concerning the species refer to it as ''Ocypode platytarsis''. In 2013, the Japanese carcinologist Katsushi Sakai and German carcinologist Michael Türkay discovered that the type specimens of ''Ocypode brevicornis'' and ''Ocypode platytarsis'' belonged to the same species. They restored the validity of the earlier name ''Ocypode brevicornis''.〔
''Ocypode brevicornis'' has also been frequently confused with ''Ocypode ceratophthalma'', due to the fact that both species possess elongations of their eyestalks (styles). The variety ''Ocypode brevicornis'' var. ''longicornuta'' described by the American zoologist James Dwight Dana is now known to be a synonym of ''Ocypode ceratophthalma''.〔
''Ocypode brevicornis'' belongs to the genus ''Ocypode'' of the ghost crab subfamily Ocypodinae in the family Ocypodidae.
