Let’s see a show of hands, Pandas: how many of you love animals? Uh-huh, uh-huh, it’s just as we suspected—a whopping 159% of you are huge fans of the animal kingdom! Whether it’s cats, dogs, rabbits, or horses, we know for a fact that they matter to you just as much (and sometimes even more than) other people. But just how much do we really know about the animal kingdom?

When you start digging deeper, you realize that other living beings can be just as weird, if not weirder than, people themselves. Odd behaviors, character quirks, and peculiar instincts make for a better story than some of the fiction novels we’ve seen coming out in recent years. So today we’ll be diving headfirst into the world of obscure animal facts, courtesy of the knowledgeable trivia and biology experts over on r/AskReddit.

Check out the coolest facts below, upvote the ones that you didn’t know, and let us know in the comments if you’ve got some other interesting tidbits to share with the class. Oh, and you should definitely consider dropping some of these tasty info morsels at the next dinner party you go to—there’s nothing like bragging to your fellow Ravenclaws to make you seem like the next Attenborough. (Just remember to keep flapping your arms like a fashion chicken as you recite what you know.)

35 Interesting And Weird Animal Facts Not Too Many People Know All the deep sea anglerfish you see pictures of with the lil lights hanging over their heads? They're all female.

The males are tiny and born with a terribly weak jaw and a massive hunger. They seek out a female, and torn between hungry and horny they bite her.

She then releases an enzyme that fuses the male to her body. She slowly absorbs them into her body with only their lil testicles remaining so she can instantly fertilize her eggs when she wants to.

Some females have rows and rows of lil testicles on their bodies from where they have absorbed multiple males.

And you thought your sex life was weird, eh?

But no kink shaming.

Steven Wooding, from the Institute of Physics in the UK, recently shared with Bored Panda a cool animal fact that he thinks others should know, too.

“Crows are the Einsteins of the bird world. Expert at solving puzzles, and they can even recognize your face. They will actively avoid individuals who have been aggressive toward them in the past," he told us that we should never underestimate crows. Ca-caw indeed.

Meanwhile, Dr. John W. Wilkinson, from the Amphibian and Reptile Conservation charity in the UK, told Bored Panda that learning about animals can help inspire us to protect them. He said that people sharing photos of animals can create a deeper interest in them and their conservation. So long as the wildlife doesn’t get disturbed too much.

If you happen to have a garden, one way that you can help your local amphibians and reptiles (we hear they’re very polite) is by building a garden pond for them. That and not using chemicals are two ways that you can really help out the life growing in your garden.

35 Interesting And Weird Animal Facts Not Too Many People Know In Africa certain tribes communicate directly with birds called Honeyguides letting them know they are ready to hunt. The honey guides then lead them to hidden beehives in trees. The tribesmen break open the hives and take the honey( an important resource in their diet) and leave the honeyguides the bee larva and wax to feast on. In fact, it’s the only known example of targeted two-way signals between people and a free-living species.

"In a small garden, even an upturned dustbin lid or bowl will provide a place for animals to drink," Dr. Wilkinson explained to us that if space is an issue, even something as small as this can help. If you have more space, you can make a compost heap or build a log pile.

"Climate change can be a very negative factor for frogs, toads, and newts. Ponds can dry up too quickly, meaning their tadpoles don’t have enough time to develop. Also, warmer winters affect hibernating frogs. They use more energy during hibernation and partially wake up, meaning they are in poorer condition for breeding. This is particularly hard on the females who put a lot of energy into making eggs (spawn)," the wildlife expert stressed that climate change is having a massive impact on local critters.

35 Interesting And Weird Animal Facts Not Too Many People Know Every once in awhile, an emperor penguin will do something very strange. Most of them will never do this, but the ones who do have stumped scientists for awhile now.

Every once in awhile, a penguin will turn away from its colony and start heading for the interior of the continent (Antarctica). Away from the food, the water, the safety of the colony. Off alone towards certain death. Almost like zombies. In the past, scientists would try to stop them. Or take them back to the colony. At which point, they'd simply turn around and begin their journey again, in the same direction, toward the same end. Some would even get violent if they were met with intervention.

The prevailing thought is that this penguin is depressed and is committing suicide in a very non-altruistic manner. But nobody knows for sure. There are a lot of possible explanations for this (including the possibility of a fungal infection similar to the cordyceps infection that can cause some colony insects to behave in exactly the same way, potential signs of brain tumors or other medical conditions that the birds are exposed to) It's well known that birds can experience depression or anxiety, but they tend to respond to this in very immediate ways, such as by over-preening (pulling out their own feathers), screaming, or being unusually quiet, loss of appetite, etc. (Bird anorexia is a MAJOR thing) These activities are signs of redirecting stress, while wandering off into the abyss of an unforgiving frozen continent implies the ability to analyze and think ahead in a way that most birds really don't seem to be able to do. So the reason may not be as immediately obvious as you might think.

From what I know, no autopsies have been performed on these rogue penguins. Most likely because the conditions are too harsh to hunt their corpses down. But until one is performed, we really have zero idea why they do this. And yet they do. And the behaviour is common enough that it's been documented multiple times.

35 Interesting And Weird Animal Facts Not Too Many People Know The vast majority of Greenland sharks are blind thanks to a special parasite that eats their eyes and replaces them.

It is thought that this might actually be helpful because a) their eyesight was s**t anyway, b) the parasites wave like lures and may have an anglerfish-like effect, and c) the sharks are super slow so that might be one of the few ways for them to catch live prey.

Imagine something eating your eyeballs and it being an *upgrade*.
