Atlantic Chub Mackerel

Açıklama

Scomber colias, commonly known as the Atlantic Chub Mackerel, is a pelagic schooling fish belonging to the family Scombridae. It is characterized by its streamlined, fusiform body, typical of fast-swimming oceanic predators. This species is an important component of marine ecosystems, serving as both a predator of smaller organisms and a prey item for larger fish, marine mammals, and seabirds. It is also a commercially significant species in many parts of its range.
