SEALS
DESCRIPTION
Seals, commonly known as true seals or earless seals, are marine mammals characterized by their streamlined bodies and lack of external ear flaps. They have a thick layer of blubber that helps insulate them in cold waters, and their forelimbs are modified into flippers, making them agile swimmers. Seals are often found resting on ice or beaches, and they are known for their playful behavior and social interactions, particularly during breeding seasons.
FUN FACTS
- Seals can hold their breath for up to 30 minutes while diving, allowing them to reach depths of over 600 meters in search of food
- | Some species of seals, like the harbor seal, are known for their unique vocalizations, which can sound like barking or even singing, and are used for communication among individuals
