The round herring (Dussumieriidae) are a family of herring-like (Clupeiformes) which live as schooling fish pelagic on the coasts of subtropical and tropical seas and feed on zooplankton . Their eggs are also pelagic. The group was previously assigned to the herring (Clupeidae) as a subfamily , but today, limited to the two genera of the former Dussumieriini tribe, it has family status as a sister group of the wolf herring (Chirocentridae).

distribution

Round herrings occur in the tropical and temperate Indo-Pacific , in the eastern Pacific and in the western Atlantic, as well as in the Red Sea . Two species have also reached the eastern Mediterranean through the Suez Canal.

features

Round pegs are small to medium-sized schooling fish and grow to be 14 to 33 cm long. In contrast to all other herrings, apart from a W-shaped scale at the base of the pelvic fin, they are completely free of scales. They have numerous Branchiostegal rays (11 to 18). Your premaxillary is rectangular.
