Habitat
Weddell seals primarily inhabit the Antarctic pack ice and fast ice areas, preferring stable ice platforms for breeding and resting. They are found in coastal regions and on ice shelves around the Antarctic continent, tolerating extreme cold and icy conditions. Geographic range is limited to the Southern Ocean and adjacent lands.
Diet
Weddell seals mainly eat fish such as Antarctic cod, along with squid and krill, which they hunt by diving to depths of up to 600 meters. They are benthic feeders, often foraging on the ocean floor during the day or night. Feeding behavior includes holding their breath for over an hour during dives.
Behavior
Weddell seals are social animals that form groups on ice floes, especially during breeding season, and are known for their loud underwater vocalizations used for communication. They are mostly diurnal but can be active at any time, spending much of their day hauled out on ice to rest or thermoregulate. They exhibit minimal territorial behavior, though males may defend small areas during mating.
Conservation Status
The IUCN status of the Weddell seal is Least Concern, with a stable population trend. Major threats include climate change, which reduces ice habitats, and potential disturbances from human activities in Antarctica.
