Etymology: Grammonus: Greek, gramma = signal, mark + Greek, onos = hake; minutus: The specific name, minutus, refers to the
short length at which the males attain maturity and ripen (Ref. 84063).

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
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.
Body shape (shape guide): short and / or deep.
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).
