Something Tastes Fishy
Our first entry on our list of fun facts about animals addresses catfish.

The taste buds are predominantly found in the whiskers, but the catfish also have their taste buds along the length of their body. It allows them to be able to taste when their dinner is close.
Worlds Tiniest Superhero
Tardigrades are one of the most robust animals on Earth. They can survive in almost any environment, including the vacuum of outer space.
When it comes to strange but fun facts about animal kingdom, few things beat sharks.
Sharks have two extra senses. They can detect the smallest electrical charges in the water, including those from muscle contractions. They are also able to feel changes in water pressure and movement. These allow the shark to navigate and hunt in the low light or when its vision is impaired.
However, it is more likely to be bitten by a New Yorker than a shark, and that is saying something about New Yorkers, really.
Letting Your Skin Breathe
Frogs breathe through their skin.
It is not likely a vital function, but more of an accidental coincidence. Frogs can breathe through their skin as a result of the blood flowing so close to the skin surface that it allows the absorption of oxygen.
Dropping Weight Wherever You Can
Birds have hollow bones, which allow them to fly.
Surprisingly, this doesn’t make them much lighter because they need to be dense to stop from breaking. Instead, the bones help with oxygen delivery to muscles during flight.
A Little Hum
The smallest bird egg is the size of a pea.
It belongs to the bee hummingbird, and it weighs the same as a single grain of rice.
The bee hummingbird is also the lightest bird in the world; an adult weighs the same as a penny.
Stranger Things to Bite with
Next on our list of fun facts about animals is about hydras and the fact that they tear open their mouths to consume their food.
Hydras are small freshwater animals that attach to rock surfaces and rely on the water current to deliver their food. They have a mouth area ringed with tentacles to catch and paralyze any prey that gets to close. Then this happens a chemical and neurological process occurs that causes the cells at the mouth surface to change shape and pull apart.
After indulging in their meal, they expel any waste in the same process.
The horned lizard will shoot blood tears when threatened by predators.
The horned lizard is unlikely to use this defense against us humans as it seems to save its ammunition for its real predators.
Abominable Snow Dog
Wolverines have frost resistant fur and teeth that can easily tear frozen meat.
Wolverines are found in alpine tundra and need to deal with below freezing temperatures. They have adapted to this environment by coating their fur in oil that stops it from freezing and having specialized sideways molars that let them tear into meat that has frozen solid.
Silent But Deadly
Barn owls make almost no noise while flying.
Owls can easily be one of the most beautiful animals, but also one of the most terrifying! They are known for having fantastic eyesight and hearing, but it is also their near silent flight that they need to thank for their midnight snacks.
These Teeth Were Made for Chomping
Beavers have teeth reinforced with iron.

Penguins are adorable on the outside, but nightmare fuel on the inside. Their throats present spike-like structures called papillae that stop fish from leaping back out of their mouths. And speaking of penguins, did you know that some ancient penguin species – namely, the Kupoupou stilwelli – ruled the Earth after the dinosaurs’ extinction? No wonder they were some of the top predators of those times with those inner spikes…

Dyer – one of the researchers involved in the study of bees’ math skills – when we presented you with our selection of 100+ weird science facts to enrich your general knowledge.

It then takes up residence in the fish’s mouth as its new tongue; it uses this as an opportunity to make the fish do all the work to find the food and the louse steals the reward.
Made to Fit
Turtles have their ribs fused to their shell.
This “building” ensures that the shell doesn’t go anywhere and helps distribute its weight. It also prevents their ribs from moving even while breathing.
Antsle and Gretel
Ants compute. Somehow. They count their steps so they can find their way back to their nest later. Speaking of ants and steps, remember that recent studies showed that ants control and organize their own traffic, being able to keep consistent movement at 80% density, putting humans to shame.
The next fun fact about animals is a piece of legend and history that is equally true and embarrassing for Australians. You can put this gem of information in your animal trivia baggage and call it a day.
Armed soldiers were sent to defend agricultural land from emus – the soldiers lost.
In the 1930s emus posed a threat to the agricultural success of Australia. They tore down fences and ate crops. The Australian government sent in soldiers with light machine guns to cull the birds. It was a massive failure with only one bird dying for every 250 bullets fired. The birds proved faster and smarter than the soldiers ever believed.

Eggs + Milk = A Happy Hatchling
There are a few birds that can produce “milk” to feed their young.
It is not the same as mammalian milk but serves the same purpose. Flamingos, doves, and pigeons are among the few birds who can secrete fluid-filled cells from the back of their throats to feed their hatchlings.
The beak of a sword-billed hummingbird can reach 10 cm long. That’s longer than its body.

Whales and dolphins are related to land mammals that returned to the sea. Another fun fact is that they have maintained the same bones in their forelimb. It means that they have the same bones as us humans, but have arranged them differently.
Food for Thought
Last but not least on our top fun facts about animals involves mealworms and the fact that they can absorb memories from eating other mealworms.
Mealworms were given a maze to complete; when finished, they became food for the next group of mealworms. The worms who ingested mealworms who had already completed the maze performed significantly better than the control group, suggesting that the memories of directions of the maze were somehow transferred to the consuming mealworm.
