Black Skipjack
Euthynnus lineatus
Euthynnus lineatus, the black skipjack tuna or black skipjack, is a species of ray-finned bony fish in the family Scombridae. It belongs to the tribe Thunnini, better known as the tunas. It is in the genus Euthynnus of "little tunas" which includes the little tunny from the Atlantic Ocean and kawakawa, from the Indo-Pacific Ocean, which also shares some range with the black skipjack.

Description
E. lineatus has a total of 10-15 spines in its dorsal fins with the anterior spines of the first dorsal fin being much taller than the middle spines which gives this fin a concave outline. The anal fin has 11 - 12 soft rays and it has a vertebra count of 37. Its body is almost entirely scaleless except for the lateral line and a "corselet", and there is no swim bladder. It is generally iridescent blue in colour with black markings on its back made up of 3 to 5 horizontal stripes, as well as a variable amount of black or dark grey spots above the pelvic fins. Occasional specimens have extensive longitudinal stripes of light grey on their belly while other individuals have few or no such markings. After death, the lines are often no longer prominent, but can still be distinguished by the 2 or more spots over the pelvic fins. E. lineatus can reach up to 92 centimetres (36 in) and a weight up to 11.6 kilograms (26 lb).
