The wolf herring ( Chirocentrus ) are a genus of herring-like predatory fish. These fish have relatively long bodies. They live in warm shallow waters from the Red Sea to Japan and Australia .
features
There are two species that grow to about three feet long and are silvery in color with a bluish back. Your body is elongated and heavily compressed on the sides. The edge of the abdomen forms a sharp keel. The scales are small, the dorsal fin stands above the anal fin and has 16 to 18 fin rays . The pelvic fins are small. The jaws have long, sharp fangs and fine brush teeth.
The genus Chirocentrus is the only recent member of the family Chirocentridae. Gastroculpa is still known from the Upper Cretaceous of Bolivia . Chirocentrus has some reputation in fish anatomy because it is said to be the only Teleostar whose midgut still shows traces of the spiral intestine , as most primitive fish (e.g. the sharks ) have. But in truth there is only a shallow circumferential furrow (for surface enlargement), which has nothing to do with approx. 40 turns with the spiral intestine of Amia, for example .
