15 Unusual Animal Facts That Will Blow Your Mind

  1. Octopuses have three hearts
    Two pump blood to the gills, one pumps it to the rest of the body—and their blood is blue, not red.
  2. A group of flamingos is called a “flamboyance”
    And when they gather, it’s as fabulous as it sounds!
  3. Wombat poop is cube-shaped
    This oddball adaptation helps prevent their droppings from rolling away, so they can mark their territory.
  4. Sloths can hold their breath for up to 40 minutes
    They slow their heart rate and chill underwater, making them surprising swimmers.
  5. Turritopsis dohrnii, the “immortal jellyfish,” can theoretically live forever
    It can revert its cells back to an earlier state and start its life cycle over again.
  6. Elephants can “hear” with their feet
    They pick up vibrations from the ground using sensitive cells in their feet and trunks.
  7. Male seahorses get pregnant and give birth
    In the animal kingdom, it’s the dads who carry and deliver the babies!
  8. Froghoppers (spittlebugs) are the best jumpers in the animal world
    They can leap over 100 times their body height—far out-jumping fleas or grasshoppers.
  9. Starfish (sea stars) have no brains or blood
    They use a water vascular system to move nutrients around and “think” with a network of nerves.
  10. A shrimp’s heart is located in its head
    Just one of many bizarre crustacean quirks.
  11. Cows have best friends and get stressed when separated
    They’re more social (and emotional) than they get credit for.
  12. Axolotls can regenerate entire limbs—and even parts of their brain
    Making them the ultimate animal healers.
  13. Penguins propose with pebbles
    A male penguin gives his mate a smooth stone as a “gift” during courtship.
  14. Orcas are actually dolphins
    Despite being called “killer whales,” they’re the largest members of the dolphin family.
  15. Turritopsis dohrnii, the “immortal jellyfish,” can theoretically live forever
    It can revert its cells back to an earlier state and start its life cycle over again.
