📖 1. Overview

The capelin is a small schooling fish living in cold waters around the Arctic Ocean. During the spawning season, large schools gather along the coast and sometimes enter brackish and fresh waters.

🦴 2. Anatomy & Morphology

Its body is shaped like a long rod, dark gray on the back and silvery white on the belly. There is an adipose fin behind the dorsal fin, and males have an elongated ridge of belly scales and longer anal fin rays than females.

🔍 3. Ecology & Behavior

It feeds on planktonic crustaceans such as copepods, as well as krill, marine worms, and small fish. In spring, spawning schools migrate toward the coast and attach their eggs to sandy and gravelly bottoms, typically dying after spawning once.
