Macrophthalmus pacificus is a species of sentinel crab found widely across the Indo-West Pacific Ocean, including India, Japan, Malaysia, New Guinea, Solomon Islands, and northern Australia.[2] In Australia it is found in the north from northern New South Wales to around Exmouth in Western Australia.[1] M. pacificus lives in mud in tidal zones of river mouths' adjacent mangrove forests in low tide areas. The claws of adult males are sky blue.[3] It is often found feeding in shallow still water, and in soft mud.[4]: 2 The upper claw of males has a tooth on the upper claw (dactyl). Like other Macrophthalmus species, the claws of the male are larger than those of the female.[3] The carapace is smooth and shiny, up to around 25 mm across.[5] A synonym of Macrophthalmus pacificus is Macrophthalmus bicarinatus.[1]
