Pleurosicya mossambica

Pleurosicya mossambica is known by a wide variety of common names, including the toothy goby, common ghost goby, ghost goby, gudgeon, manyhost cling-goby, manyhost goby, Mozambique ghost goby, and reef goby.[3] Its generic name, Pleurosicya, is derived from the Greek pleura, meaning side, and sikya, as in cucumber.[4] Its species name, mossambica, refers to Mozambique, the region in which it was first discovered.

Pleurosicya mossambica is a small goby, growing to a maximum recorded length of 3 cm (1 in). It is a pale red in coloration, and the body is partially translucent. It has seven dorsal spines, seven to eight dorsal soft rays, one anal spine, and eight anal soft rays.[4] The eyes are prominent with red and yellow rings, and are positioned at roughly 45 degrees on each side of the head to allow it a greater field of vision. Their pelvic fins have evolved into sucker-like appendages, which allow them to attach themselves to corals in high-current areas.[5]

Pleurosicya mossambica is native to the greater Indo-West Pacific region. The limits of its range extend as far west as the Red Sea and the eastern African coastline, as far east as Fiji and the Marquesas Islands, as far north as southern Japan, and as far south as southeastern Australia and New Caledonia. It can be found in coastal bays and reef slopes, most commonly near one of its many hosts, at depths between 2 and 30 m (10 and 100 ft).[4]
