SEAL
DESCRIPTION
Seal is commonly known as true seals or earless seals. These marine mammals are characterized by their streamlined bodies and lack of external ear flaps, which distinguishes them from other pinnipeds. Seals are highly adapted to life in the water, with a layer of blubber for insulation and powerful flippers for swimming, making them agile hunters in their aquatic environments.
FUN FACTS
- Seals can hold their breath for up to 30 minutes while diving for food, thanks to their ability to slow their heart rate and redirect blood flow to vital organs
- | Some species of seals, like the elephant seal, can weigh over 4,000 pounds and are known for their impressive size and vocalizations, which can be heard from miles away
