Did you know World Snake Day takes place every year on July 16? To celebrate, here are five fun facts about these slithery reptiles:

1. All snakes are carnivores.

That means all snakes eat meat. In particular, they may eat mammals, birds, reptiles, amphibians, eggs, worms, and insects. Watch this video of an egg-eating snake swallowing a large egg whole:

2. There are over 3,000 species of snakes.

Some species, like the Barbados threadsnake, are as small as 10 cm (4 in.) fully grown. Others, like the reticulated python, can grow to be over 6 m (20 ft.) long.

3. Some snakes are venomous.

That means they produce a toxic saliva. Usually, the venom is injected into their prey through their fangs, though some species spit the venom.

4. Baby snakes are called snakelets.

Some baby snakes hatch from eggs their mothers lay. Some snakelets hatch from eggs inside their mothers’ bodies. And some snakelets are born live (with no eggshell).

5. Snakes can’t blink.

They do not have eyelids. Instead, they have a clear membrane that covers their eyes called a brille.

In honor of National Panda Day, celebrated every year on March 16, here are five cool facts about giant pandas!

1. Giant pandas have special “thumbs.”

One of the interesting evolutionary traits of the giant panda is their protruding wrist bone that acts like a thumb. This helps the pandas hold bamboo while they munch on it.

2. Pandas eat a massive amount of bamboo every day.

Due to the low nutritional value of bamboo, pandas need to eat 10-20 kg (20-40 lb.) of bamboo a day. They spend up to 16 hours of the day eating!

3. Pandas often sound like goats or sheep.

The most common sound a panda bear makes is a bleating sound, similar to that of a goat or sheep. But they can make a variety of sounds, including honks, huffs, barks, squeaks, and growls.

4. Pandas use their heads to help them climb trees.

Researchers at the Chengdu Research Base of Giant Panda Breeding in China observed panda cubs climbing trees. They found the most effective climbers used their heads to help hug and grip the tree trunk as they shinnied up.

5. Sometimes male pandas pee while doing handstands.

Pandas mark their territories with scents. They have scent glands on their rumps which they rub on trees, rocks and the ground. They also scent mark with urine. Sometimes male pandas do handstands so they can leave their pee high up on a tree trunk!

Every year, World Whale Day takes place the third Sunday in February. This year, it falls on February 15, 2026. To celebrate these amazing marine mammals, here are five cool facts about the largest whale in the world: the blue whale.

1. Blue whales are the largest animals to ever live on Earth!

Imagine three school buses lined up end to end. That is the length of a blue whale. They can be as long as 33.5 m (110 ft.) and weigh more than 150,000 kg (330,000 lb.). They are even bigger than all the dinosaurs we know about!

2. Blue whale blowholes look like human noses.

Like all whales, blue whales have blowholes at the top of their heads so they can breathe air when they come to the surface. However, blue whales have a pair of blowholes instead of just one, like most whales.

3. Blue whales are really loud.

Blue whales communicate in whistles, pulses, groans and moans. In ideal conditions, their calls can be heard up to 1600 m (1000 mi) away! They are 188 decibels, which is louder than a jet engine. Along with sperm whales, they take the title as the world’s loudest animals.

4. Blue whales have really stretchy throats.

Blue whales have pleated throat grooves which allow their throats to expand four times their original width! In fact, blue whales double their volume when they inflate their throats with water and food.

5. You can tell a blue whale’s age by its ear wax.

Scientists have discovered that you can tell a whale’s age by counting the layers of waxlike earplugs in their ear canals. Typically, blue whales live about 80-90 years in the wild. When they looked at the layers of one blue whale’s earplugs, they determined the whale was 110 years old. That’s a lot of ear wax!

Every year on February 2, we celebrate Groundhog Day! Will the groundhog see his shadow this year? Will there be 6 more weeks of winter?

While groundhogs may not be the most accurate weather predictors, they are pretty cool animals. Here are 5 fun facts about groundhogs to celebrate Groundhog Day!

1. Groundhogs are also called whistle pigs.

They may be called whistle pigs, but they’re not pigs. Groundhogs are a species of marmot and a type of rodent. They got this name because they let out a shrill whistle when they sense danger. Groundhogs are also commonly called woodchucks.

2. Groundhog burrows have bathrooms!

Groundhogs are excellent diggers and create complex underground burrows. Their burrows can be up to 20 m (66 ft.) long and contain many tunnels and chambers, including bathrooms!

3. Groundhogs are true hibernators.

In the winter, groundhogs go into their burrows and enter into a deep sleep. Their heart rate slows from 80 beats per minute to 5. Their body temperature drops from 37°C to 3°C (99°F to 37°F). That’s barely above freezing!

4. Groundhogs can climb trees!

Sometimes groundhogs climb trees to reach apples or pawpaws (a kind of fruit).

5. Groundhogs gorge themselves in the spring and summer.

To build up a layer of fat in preparation for their winter hibernation, groundhogs eat at least half a kilogram (1 lb.) of vegetation per day in the spring and summer! Luckily, they have teeth that never stop growing to keep up with the constant wear and tear.

Here’s something to shout about: Penguin Awareness Day takes place every year on January 20! Photo by Mario_Hoppmann / iStock.com.

Every year on January 20, we celebrate Penguin Awareness Day! In honor of this special day, here are five cool facts about penguins.

1. Emperor penguins don’t build nests. They use their feet as a nest!

After the female emperor penguin lays an egg, the male penguin balances it on his feet and covers it with a warm layer of feathered skin called a brood pouch. He keeps the egg on his feet for the next couple months protecting it from the harsh Antarctic ice and wind.

2. African penguins build nests out of their poop!

African penguin poop, also known as guano, is sturdy enough to provide protection from the elements, but soft enough to burrow into, which makes it the perfect material to use for a nest. But when poop isn’t available (because people have removed it), then African penguins nest primarily under bushes and boulders.

3. There is one species of penguin called the macaroni penguin.

Yes, that’s really their name, but they’re not made of noodles! Macaroni penguins are one of six species of crested penguins and have fun yellow feathered crests on their heads.

4. Gentoo penguins are the fastest of all penguins.

Gentoo penguins can reach speeds up to 35 km/h (22 mph) while zipping through the ocean. They have the ability to change the angle of their wings, called flippers, to gain maximum thrust while propelling themselves through the water.

5. Penguins don’t have teeth.

Penguins may not have teeth, but they do have sharp spiky things on their tongue and roof of their mouth. Those spines are called papillae, and they help push food to the back of the penguin’s mouth.

They’re famous for pulling Santa’s sleigh, but how much do you really know about reindeer? Read on for five fun facts about reindeer, also known as caribou.

1. Both male and female reindeer have antlers.

Reindeer are the only deer species where both the males and females have antlers. And these antlers are BIG! Reindeer have the longest and heaviest antlers of all deer. In fact, a male reindeer’s antlers can span as long as 1.3 m (51 in.)!

2. A reindeer’s antlers fall off every year.

Yes, every year, reindeer’s antlers fall off. But don’t worry! New ones grow back even larger! Male reindeer lose their antlers in November and grow them back in the spring. Female reindeer lose their antlers in May after their calves are born.

3. Reindeer have hollow fur.

Two coats of fur help keep reindeer insulated from the cold. They have a fine, wooly inner coat, and on the outside, they have long, hollow guard hairs. These guard hairs trap air to keep the reindeer warm. The trapped air also helps reindeer to float while swimming!

4. Reindeer have furry feet.

Reindeer have long hairs on their hoofs, including the bottoms of their feet! This helps keep their tootsies toasty and provides grip on the snow and ice.

5. Reindeer are the only domesticated deer species.

Wild reindeer inhabit the tundra and boreal forests of the Arctic, across North America and Eurasia. But some reindeer are domesticated! In fact, reindeer were first domesticated at least 3000 years ago by Arctic people. Domesticated reindeer are used to pull sleds and for food.

Reindeer have been domesticated for thousands of years. Pictured here are people traveling by reindeer in Russia, circa 1890-1900. Photo by Detroit Publishing Co., Public Domain, via Wikimedia Commons.

In celebration of the American holiday of Thanksgiving, here are a five cool facts about turkeys.

1. A turkey’s wattle can change color.

The flap of skin on a turkey’s chin is called a wattle. The wattle is useful for releasing heat on a hot day since turkeys cannot sweat. It can also change color! When male turkeys are trying to attract a mate, it turns bright red. And when they’re frightened, it turns blue!

2. An adult turkey has 5000-6000 feathers.

Turkeys have 8 types of feathers, which provide for insulation, flight, and ornamentation. Some feathers are iridescent, meaning their color seems to change in different lights or from different angles.

3. Turkeys can run pretty fast.

Wild turkeys trot at about 19 km/h (12 mph). But when frightened, they can reach speeds as fast as 40 km/h (25 mph)!

4. Wild turkeys can swim.

Although wild turkeys typically walk or trot, they can also fly (ungracefully) and swim!

Watch a video of a wild turkey swimming across a pond:

5. Turkeys can lay fertilized eggs without mating.

Usually, you need both a male and female turkey to produce a chick. But female turkeys can lay fertilized eggs even when they don’t mate. This process, called parthenogenesis, also occurs in some invertebrates, fish, and lizards. (See our article about Komodo dragons for another example.) For turkeys, this process always produces male chicks.

5 Cool Facts about Bison for National American Bison Day

American bison

To celebrate National American Bison Day, which takes place on the first Saturday in November every year, here are five cool facts about bison:

1. Though often called a buffalo, the American bison is not a true buffalo.

The only true buffaloes in the world are the water buffalo and the African buffalo. American bison are not closely related to either of those. Instead, they are large ungulates (hoofed mammals) that live in the plains of North America.

Still, the name ‘buffalo’ is commonly used when referring to American bison and is typically accepted.

2. Both male and female bison have beards.

Yes, both male and female bison have long, scraggly hair on their chins and necks. They both also have horns! You can tell male and female bison apart by their size. Male bison are larger than females, weighing up to 900 kg (2000 lb.)!

3. Baby bison don’t have humpbacks.

Newborn bison lack the distinctive hump of the adult bison. They begin developing the hump after a few months.

4. American bison are pretty fast!

Although they are the largest land mammal in North America, American bison are surprisingly speedy. They can run up to 56 km/h (35 mph).

5. You can tell a bison’s mood by its tail.

When a bison’s tail is down, they are calm. But if you see their tail up, watch out! They are about to charge.
