Common minke whale (Balaenoptera acutorostrata) is one of the smallest rorquals (family Balaenopteridae), widespread in the North Atlantic and North Pacific. It feeds on small schooling fish and krill via lunge‑feeding with expandableventral pleats. IUCN: Least Concern (LC).
Identification
Length 7–10.7 m, mass ~4.5–10 t; dark‑grey back, white belly; pectoral white band common; falcate, forward‑set dorsal fin;50–70 ventral grooves; low blow.
Ecology
Prey includes sand lance, herring, capelin, mackerel and euphausiids; mostly solitary or in small groups; uses lateral lunges, shore‑drives and tidally‑driven fronts for efficient feeding; dives typically a few minutes, up to ~15 min.
Threats & Measures
Whaling pressure persists in some regions (historical & present).
Entanglement in fixed gear and ship strikes.
Noise and climate‑driven shifts in prey/habitats.
Measures: dynamic protection of feeding/migration corridors, vessel speed/routing, quieter‑ship initiatives, and ropeless gear pilots.
