Grammonus minutus Nielsen & Prokofiev 2010

Grammonus minutus differs from the nine described Grammonus species since it exhibits the following combination of characters: fin rays in dorsal 75–76, anal 54–55, pectoral 22–23, number of vertebrae 12 + 30, interorbital 7.4% of SL. Males have already reached maturity by a length of 32 mm SL.

Caught in a shrimp trawl working on the muddy bottomat a depth of 70–119 m (Ref. 84063).

Depending on the changes in the current system in the Bay of Nha Trang and adjoining areas, juveniles and adolescents of deep-water fishes occur in the collection area at these shallow depths. According to T.T. Hieu, Institute of Oceanography, Nha Trang (personal communication, 2009), there are a number of deep canyons cutting into the outer shelf, which explains the capture of many relatively deep-living species. It is thus possible that G. minutus may live deeper than indicated by the actual trawling depths (Ref. 84063).
