Details

Habitat

Its range is represented here by Antarctica and the Southern Ocean, where it uses polar habitats, coasts and open ocean. Mobile species may shift habitat use with season, breeding sites, or food availability.

Appearance

Typical length 250-350 cm, weight 400 kg-600 kg. It has a long-bodied carnivore profile, with proportions shaped by its habitat and mode of movement.

Behavior

It is active in bouts across day and night and often found in loose groups. Spacing, group size, and visibility can change with season, feeding conditions, and breeding activity.

Feeding

It is carnivorous. Food choice and foraging style are tied to life in polar habitats, coasts and open ocean, so movements often follow available food resources.

Reproduction

As a mammal, it gives birth to live young, and the mother nurses them in cover or within the social group.

Notes

Recorded scientifically as Leptonychotes weddellii. It remains widespread in parts of its range, but local habitat change still matters. In this guide, size, habitat, and activity pattern are useful first clues for recognition.
