The gnome fish ( Scombrops ) are a genus of perch-related marine fish. It occurs in the tropical, western Atlantic , western Pacific and Indian Oceans .
features
Gnome fish are one to 1.5 meters long. Your eyes are relatively large. They have two dorsal fins. The dorsal fins are supported by seven to ten fin spines and 12 to 14 soft rays. The anal fin has three spines and 11 to 13 soft rays. The soft radiating part of the dorsal and anal fin is scaled. The pectoral fins have a black spot on the base of the fin.
Systematics
The external system of the genre is disputed. It was placed in the Pomatomidae family in the 1994 edition of Joseph S. Nelson's standard work on fish systematics , and in the fourth edition from 2004 in its own, monogeneric family. Other authors suspected a relationship with the mackerel-like (Scombroidei). The fish systematist Ricardo Betancur-R therefore assigned them in his systematics of bony fish to the order Scombriformes , without including them in his investigations, i.e. H. analyze the DNA of the fish and compare it with that of other species of mackerel. Heemstra assigned the genus to the lantern bellies (Acropomatidae). A closer examination of the relationships was carried out by W. Leo Smith and his team, who identified the family Acropomatidae as a sister group of Scombrops and assigned the family Scombropidae to the order Acropomatiformes (Pempheriformes in Betancur-R et al.).
