12 Surprising Facts About Weird Animals

1. Do earthworms really have five hearts?

You have one heart in the middle of your chest. An earthworm has a whole pump team. Earthworms have five pairs of aortic arches — think of them as five little bicycle pumps wrapped around a smoothie straw (the food tube). Those pumps squeeze together to push blood along while the worm wiggles through dirt.

2. How do ants hear if they do not have ears?

Ants do not have external ears or eardrums on their heads. Instead, ants sense vibrations through special organs on their legs and feel sound waves traveling through the ground. This helps them stay aware of approaching danger and communicate with their nestmates. Meet a giant rainforest ant in our biggest ant guide.

3. Why do only male crickets make chirping sounds?

If you hear a cricket chirping on a warm summer evening, you are listening to a male cricket! Only male crickets chirp by rubbing their textured wings together to create sound patterns. Female crickets use sensitive hearing organs on their front legs to locate the males.

4. Can snails really rest inside their shells for a long time?

Snails do not sleep for years without ever waking like a fairy-tale spell. Still, some snails can seal their shells and rest for many months when the weather turns dry. Mucus forms a protective door so the snail can wait for rain before sliding out again.

5. Why are leeches such strange soft-bodied animals?

Leeches are cousins of earthworms, but their bodies are built for sticky travel. Leeches have suction cups and many body segments that help them cling, stretch, and move. Like worms, they pump blood with a chain of tiny heart-like structures instead of one big heart.

6. Do jellyfish have hearts and brains?

Jellyfish look simple, but they are full of surprises. Jellyfish have no heart and no brain, yet some species can sense light with many eye-like spots. They move by pulsing their bell and catching food with trailing tentacles.

7. What makes emus such unusual birds?

Emus are giant birds that never take to the sky. Emus cannot fly, but they can run very fast on strong legs, and father emus often guard the eggs. Their soft double feathers also help them handle both heat and cold in Australia.

8. Why do chinchillas take dust baths?

Chinchillas have some of densest fur of any land mammal. Water can trap moisture in that thick coat, so chinchillas clean themselves with fine dust baths instead of soapy water. Rolling in dust keeps their fur fluffy and dry.

9. How many hearts does an octopus have?

Picture a swim team with three helpers. An octopus has three hearts that move its blue blood. Two hearts are like water-fillers: they push blood through the gills to pick up oxygen. The third heart is the coach: it sends that oxygen-rich blood out to the arms and body. You can learn even more about these sea creatures by reading amazing octopus facts.

10. Where does a woodpecker fit its super long tongue?

Woodpeckers need long tongues to pull insects out of tiny tree bark crevices. To store this massive feature, a woodpecker’s tongue wraps all the way around its skull inside its head. This amazing structure acts like a built-in safety helmet to protect its brain while pecking hard wood.

11. Can hummingbirds actually fly backwards?

Hummingbirds are true acrobats of the bird world. Hummingbirds can fly backwards, sideways, and even upside down thanks to unique shoulder joints that allow their wings to rotate in a full circle. This maneuverability lets them hover motionless while feeding on flower nectar.

12. Why are flamingos not born pink?

Flamingo chicks hatch with fluffy gray or white feathers! Flamingos turn pink over time from eating food high in natural pigments called carotenoids. Algae and small crustaceans in their diet build up in their feathers, slowly changing their color to bright pink.
