  1. Ancestral Roots: The ancestors of sea lions were originally land animals, similar to bears.

  2. Pinniped Distinction: Both sea lions and seals are marine mammals called “pinnipeds,” but they have distinct differences:

    • Sea lions are brown, bark loudly, “walk” on land using large flippers, and have visible ear flaps.
    • True seals have small flippers, wriggle on land, and lack visible ear flaps.
  3. Newborn Sea Lions: Baby sea lions weigh about 13-20 pounds and are 2.5 feet long when born. They are fully furred and can see.

  6. Whisker Navigation: A sea lion’s whiskers function as a navigation system. Without them, they would get lost quickly.

  7. Social Creatures: Sea lions are incredibly social animals. They love lying next to each other and even on top of each other.

  8. Built-in Heating and Cooling: A sea lion’s flippers act as a built-in heating and cooling system. Blood vessels constrict in cold weather to conserve heat and circulate to cool down in warm conditions.

  9. Built-in Heating and Cooling: A sea lion’s flippers act as a built-in heating and cooling system. Blood vessels constrict in cold weather to conserve heat and circulate to cool down in warm conditions.
