This long bright silver fish is a fish swimmer and lives in small schools, or
alone, throughout the mid-depths of the North Atlantic Ocean. It is found from
the Davis Strait south to Georgia, usually at depths between 200 and 1000 m, but
younger individuals are found in shallower water. Sometimes, in the north, this
cold-loving species ventures into waters as shallow as 64 m. Because of this,
it is one of the more commonly encountered barracudina species at high latitudes.
It uses its speed to catch small fishes and crustaceans, and, in turn, is an important
component in the diet of Atlantic cod, swordfishes, redfishes, and seals.
The white barracudina is distinguished from other species by its pectoral fins,
which are shorter than its anal fin, by the teeth on its lower jaw that have smooth
rather than ragged edges, and by the presence of scales on its body. Its anal
fin has many rays and thus extends along the body for some length, ending close
to the caudal fin. This fish also has a black band of colour on its back and reaches
about 30 cm in length.
