Dorab wolf-herring
Species of ray-finned fish
The dorab wolf-herring (Chirocentrus dorab) is a fish species from the genus Chirocentrus of the family Chirocentridae.[3] It is a coastal fish, silvery below and bright blue above. It is found in both marine and brackish or estuarine waters, feeding on smaller fish and possibly crustaceans.[4] Chirocentrus is from the Greek cheir meaning hand and kentron meaning sting. Dorab is from the Arabic language word darrab (ضرّاب) and the word is probably a corrupted form of durubb (دُرُبّ) the name for goldfish in Arabic.[5] It has another Arabic name, lisan (لسان) [5] which means tongue.
