Pinnipeds are marine mammals adapted for both land and water, with fin-like limbs.
Pinnipeds (Pinnipedia) are a unique group of marine mammals that include seals, sea lions, and walruses. They are specially adapted for life both in the ocean and on land, with streamlined bodies for efficient swimming and limbs modified into flippers for propulsion and balance.

Examples of Pinnipeds: Pinnipedia
True pinnipeds include seals, sea lions, and walruses.
The pinnipeds are divided into three main families: Phocidae (true seals), Otariidae (sea lions and fur seals), and Odobenidae (walruses). True seals lack external ears and move awkwardly on land, while sea lions have visible ear flaps and are more agile on land. Walruses are distinguished by their large tusks and social behavior.
- True seals (Phocidae): No external ears, limited land mobility
- Sea lions and fur seals (Otariidae): External ears, excellent land movers
- Walruses (Odobenidae): Prominent tusks, thick skin, social
Walruses are distinguished by their large tusks.
