Toothy goby habitat
Pleurosicya mossambica inhabits coral reefs, coastal bays and reef slopes. It has the widest distribution and widest range of host organisms of all Pleurosicya species (Larson 1990). It is commensal, found on a variety of hosts such as soft corals, Holothurians, sponges, Tridacna clams (especially the mantle), broad-blade plants (Hoese 1986) and on algae (Kuiter and Tonozuka 2001). This a solitary species (Allen et al. 2003), that is a benthic spawner. Eggs have been observed on ascidians (Kuiter and Tonozuka 2001). The maximum recorded standard length is 3 cm (Hoese 1986).
