Antarctic Minke Whale

Balaenoptera bonaerensis

Also known as Southern Minke Whale, Dark-shouldered Minke Whale

Antarctic minke whales are sleek, fast-swimming baleen whales that navigate deep into the freezing pack ice of the Southern Ocean every summer. They feed almost exclusively on dense swarms of Antarctic krill, surfacing briefly with a pointed snout and tall, curved dorsal fin before diving back into icy waters. During winter, individuals migrate north to tropical and subtropical breeding grounds where mothers nurse their single calves.

Why interaction risk is high
Observe from a safe boat distance to prevent collision or disturbance.
Why it is dangerous
Massive body mass and sudden surfacing near vessels can capsize small watercraft or cause accidental collision.
How to recognize a risky encounter
Look for a dark grey body without white pectoral bands, a sharply pointed head, and a tall curved dorsal fin.
What to do
Keep engines neutral when whales approach and never cut across a whale's path.
What to notice
Recognizable by a sleek, dark grey body, pale grey chevron markings on the back, and white underside.
Support conservation
Follow international whale-watching protocols by reducing vessel speed and maintaining respectful distance.
Responsible observation
  • Maintain Distance: Keep boats at least 100 meters away to avoid disrupting swimming paths or feeding.
  • Watch Ice Edges: Look for narrow V-shaped blows near pack ice leads where they surface to breathe.
  • Listen for Sounds: Listen for low-frequency vocalizations or bio-sonar clicks on hydrophone equipment.
