The type specimens were found living on a single sponge in 18 m depth. Numerous other individuals were also observed at this location, and all were associated with barrel sponges, with up to about 20 individuals on a single sponge, at depths ranging from 9-30 m. The goby inhabits the outer surface of the sponge and not the hollow central cavity, and occupies the deep, convoluted ravines between the longitudinal ridges and was not seen in the shallower ravines of the sponge. It also inhabits deeper water, but usually below about 15 m compared with most Bathygobius, which are mainly confined to shallow water less than 10 m deep (Ref. 132436). Allen, G.R., M.V.
