Habitat
This species primarily inhabits the cold waters of the Southern Ocean around Antarctica, often near pack ice edges. They prefer open ocean environments and migrate to sub-Antarctic waters during winter. Geographic range extends from the Antarctic continent up to about 65°S latitude.
Diet
Antarctic minke whales mainly feed on krill, such as Euphausia superba, which they filter from the water using their baleen plates. They also consume small fish and squid when available, typically diving to depths of 100-200 meters during feeding frenzies in summer months. Feeding occurs mostly in Antarctic waters from November to March.
Behavior
These whales are often solitary or found in small groups of up to five individuals, though larger aggregations can occur during feeding. They are highly migratory, traveling north in winter and returning to Antarctic waters in summer, and are known for their fast swimming speeds up to 25 km/h. They exhibit behaviors like breaching and spy-hopping, and are generally less social than other baleen whales.
Conservation Status
The IUCN status is Least Concern, but population trends are data deficient due to challenges in monitoring. Major threats include climate change affecting krill populations and potential ship strikes in shipping lanes.
