Mar 22, 2021 · Celebrate International Day of the Seal by learning a few facts about these semi-aquatic marine mammals. Seals and sea lions belong to a group of marine mammals called pinnipeds, which means fin or flipper-footed. They are adapted for life in the ocean, but come on land for long periods of time.
Seals are marine mammals known as pinnipeds. They have flippers that help them live in water and on land. They have streamlined bodies for swimming, thick blubber for staying warm, and special features for hunting and resting.

Only true seals and walruses are found in Eastern Canadian waters. The two resident species of seal in Maritime coastal waters are the grey and harbour seal. Occasionally other (Arctic migrant) species (harp and hooded seals and walruses) are seen.
All seals and sea lions are protected under the Marine Mammal Protection Act, and some are also listed under the Endangered Species Act. Together with our partners, we work to study, protect, and conserve these unique marine mammals and their habitats.
