Fishes are a paraphyletic group and for this reason, the class Pisces seen in older reference works is no longer used in formal taxonomy.Traditional classification divides fish into three extant classes (Agnatha, Chondrichthyes, and Osteichthyes), and with extinct forms sometimes classified within those groups, sometimes as their own classes: [1]
The classification of the Indo-Pacific blue marlin (M. mazara) and the Atlantic blue marlin (M. nigricans) as separate species is under debate. [1] Genetic data suggest, although the two groups are isolated from each other, that they are both the same species, with the only genetic exchange occurring when Indo-Pacific blue marlin migrate to and ...
The skipjack herring (Alosa chrysochloris) is a North American, migratory, fresh- and brackish water fish species in the herring family Alosidae. [3] The name skipjack shad comes from the fact that it is commonly seen leaping out of the water while feeding. [4]
It is a migratory offshore fish and undergoes a daily vertical migration from the surface to the seabed at depths down to about 1,000 m (3,300 ft). It is the object of an important commercial fishery off the West Coast of the United States, and annual quotas are used to prevent overfishing.
It has relatively sharp lower lip. Generally, the fish range from 25 to 40 centimetres (9.8 to 15.7 in) in length, and weigh about 1 kg (2.2 lb). However, specimens have been recorded up to 58.5 cm (23.0 in) long and 3.4 kg (7.5 lb) in weight. [4] The maximum recorded life span of the fish is 15 years. [5]
