Animals do some pretty strange things. Giraffes clean their eyes and ears with their tongues. Snakes see through their eyelids. Some snails can hibernate for three years. But other weird animal tales are hogwash. National Geographic Kids finds out how some of these myths started—and why they’re not true.
Myth
Ostriches bury their heads in the sand when they’re scared or threatened.
How It Started
It’s an optical illusion! Ostriches are the largest living birds, but their heads are pretty small. “If you see them picking at the ground from a distance, it may look like their heads are buried in the ground,” says Glinda Cunningham of the American Ostrich Association.
Why It’s Not True
Ostriches don’t bury their heads in the sand—they wouldn’t be able to breathe! But they do dig holes in the dirt to use as nests for their eggs. Several times a day, a bird puts her head in the hole and turns the eggs. So it really does look like the birds are burying their heads in the sand!
Myth
Opossums hang by their tails.
How It Started
Opossums use their tails to grasp branches as they climb trees. So it’s not surprising that people believe they also hang from branches.
Why It’s Not True
A baby opossum can hang from its tail for a few seconds, but an adult is too heavy. Besides, says Paula Arms of the National Opossum Society, that wouldn’t help them survive. “Why would they just hang around? That skill isn’t useful—there’s no point.”
Myth
Touching a frog or toad will give you warts.
How It Started
Many frogs and toads have bumps on their skin that look like warts. Some people think the bumps are contagious.
Why It’s Not True
“Warts are caused by a human virus, not frogs or toads,” says dermatologist Jerry Litt. But the wartlike bumps behind a toad’s ears can be dangerous. These parotoid glands contain a nasty poison that irritates the mouths of some predators and often the skin of humans. So toads may not cause warts, but they can cause other nasties. It’s best not to handle these critters—warts and all!
Myth
Mother birds will reject their babies if they’ve been touched by humans.
How It Started
Well-meaning humans who find a chick on the ground may want to return the baby bird to the nest. But the bird is probably learning to fly and shouldn’t be disturbed. The tale may have been invented to keep people from handling young birds.
Why It’s Not True
“Most birds have a poorly developed sense of smell,” says Michael Mace, bird curator at San Diego Zoo’s Wild Animal Park. “They won’t notice a human scent.” One exception: vultures, who sniff out dead animals for dinner. But you wouldn’t want to mess with a vulture anyway!
Myth
Penguins fall backward when they look up at airplanes.
How It Started
Legend has it that British pilots buzzing around islands off South America saw penguins toppling over like dominoes when the birds looked skyward.
Why It’s Not True
An experiment testing the story found that penguins are perfectly capable of maintaining their footing, even if they’re watching airplanes. “But the reality isn’t funny,” says John Shears, who worked on the survey. “Low-flying aircraft can cause penguins to panic and leave their nests.”
Myth
Bats are blind.
How It Started
Often associated with darkness, witches and black magic, bats have a lot of mythology and are very misunderstood, making them seem like scary creatures of the night. Because of this, people often think bats are blind due to their hunting only at night.
Why It’s Not True
The fact is that all species of bats can see, although their vision is very poor. Instead, they have excellent senses of smell and hearing, and are able to use echo-location and sonar abilities to navigate and hunt at night. Their sonar abilities are so exceptional that they’re often better than military sonar, which is amazing for such small animals.
Myth
Owls are the wisest among birds.
How It Started
Perhaps the earliest known link between owls and wisdom is their association with Athena, as the Greek goddess of wisdom is often depicted holding an owl. With their overly large eyes and the constant serious, almost thoughtful look on their faces, owls give off the impression of wisdom, of being a cut above the rest. From legends, folklore, children’s tales to Hollywood, owls have always been the night watchmen – sometimes sinister, always smart.
Why It’s Not True
Unfortunately owls are actually placed on the lower-end of intelligent birds, with the common crow considered the wisest among birds.
