Threadfin Bream

Nemipteridae species are characterised by having a continuous dorsal fin which is supported by 10 spines and 9 soft rays while the anal fin is supported by 3 spines and 7 or 8 soft rays. In some species there is long filament growing out of the upper lobe of the caudal fin. Some species, especially in Scolopsis are protogynous hermaphrodites. These fishes vary in size from the redfin dwarf monocle bream (Parascolopsis boesemani), with a maximum published standard length of 17 cm (6.7 in), to the monogrammed monocle bream (Scolopsis monogramma) which has a maximum published total length of 38 cm (15 in).

Nemipteridae fishes are found in the Indo-West Pacific. Two species, Nemipterus japonicus and Nemipterus randalli have reached the Mediterranean Sea from the Red Sea, likely by Lessepsian migration through the Suez Canal. These are typically predatory fish feeding on benthic animals including fishes, crustaceans, polychaetes and cephalopods, however, some feed on zooplankton.
