Slow And Steady Vibes
When a female sloth wants a mate she'll hang onto a tree branch and just scream.
Bouche and Audi and Shyla, Oh My! 2 years ago
I've sat on my couch and screamed, but no one came.

Too Cute to Handle
cats have the mental capacity of a 2 year old which makes a lot of sense
troufaki13 2 years ago
I saw a documentary once that said that dogs behave like 4 year-olds, meaning they get attached to their owners just like toddlers to their parents, but cats behave like teens. They love their parents but they don't want to hang around them too much! 😅

Bubble Trouble Ahead
Polar bear fur isn't white - it's translucent (for most frequencies of light). And they have black skin underneath.
So polar bear fur lets all the light through to their black skin to warm them - except for a few visible frequencies to keep them camouflaged as white.

Silent Strolls and Snowfall
Contrary to popular belief, reindeer prefer raisins instead of carrots. So if you want to leave a treat for Santa's reindeer, leave raisins. I only know this because a friend of mine has a reindeer farm and they will push you for a whole box.
Bouche and Audi and Shyla, Oh My! 2 years ago
Good to know. Personally, I see raisins as the waste of a perfectly good grape. So, I'll eat the celery and peanut butter, and the reindeer can have the raisins.

Ocean’s Little Hideout
Argonauts are small octopuses that are too lazy to f**k. They detach their d***s and toss them into the open sea to mate with female argonauts.
#7
Low-Key But Fierce
Honey badgers can turn their a******s inside out and use the smell to deter attackers. Not sure what exactly has the guts to attack a honey badger, but if they have the courage to do so, the badger sure as hell isn’t gonna make it easy.

Ocean’s Best Comedians
Dolphins will intentionally use puffer fish to get high.

Deep Sea Acrobatics
The Blanket Octopus exhibits the highest degree of sexual dimorphism known. Females: About 6 feet across. Males: About one inch.

An ostrich's eye is bigger than it's brain

Woodpecker on a Brick Break
Woodpeckers' tongues wrap around their brains to cushion them from the vibrations of slamming their face into trees all day.
Shelli Aderman 2 years ago
Fun Internet rabbit hole I just went down. It’s not so much that they conscientiously place their tongue there. The woodpecker tongue is so long to reach insects, and when not darting into the holes of trees they’ve made, it just kind of stores itself really far up: Woodpecker...ahashi.png

Is This Otter Real?
Sea otters are the most densely furred animal with 600,000 to 1,000,000 hair follicles per square inch. Dogs have about 15,000 per square inch, humans on average are between 800 to 1,290 hairs per square inch

Silent Watcher Vibes
Owls have really long necks, but it's hard to notice that because their feathers are so fluffy
HelluvaHedgehogAlien 2 years ago
They also have really long legs and wings. But all the choose to do all day is look cute… until night comes

Delicate Design Masterclass
Dragon flys have the highest kill rate out of any flying predator.
Floeckchen 2 years ago (edited)
I think kill rate is a bit misleading here. Hunting quota might be more accurate. If a dragonfly set out to hunt its prey they have a success rate of (depending on the source) 70% up to 98%

Master of Chill Mode
Platypus glow blueish green under ultraviolet light. They also don’t have nipples, they just exude milk from glands under the skin and the baby’s lap it up.
Gandalf the Pink 2 years ago
It is also one of the only five mammals that lay eggs. I swear platypuses and octopuses are aliens on Earth...
#18
Underwater Oddball
Male anglerfish are super teeny tiny compared to a female. When a male finally bumps into a female down in the deep deep dark, he attaches himself to her and slowly, over time, he becomes A PART OF HER
#19
Curiosity Wins Again
Does will eat their offsprings feces in order to keep predators from even recognizing there are babies around.

Lines That Tell Stories
Humans have stripes. They are rarely visible but we all have them due to how our bodies developed in the womb. They're called Blaschko Lines

Snap Judgment
Mantis Shrimp have 16 different sets of rods.
(Rods and cones are in your eyes. Cones see light, rods see color. Humans have 3 sets of rods, red blue yellow.)
Mantis Shrimp are seeing colors we can not.
That’s not even the strangest thing about them. They can also punch as fast as a .22 bullet which cause a cavitation bubble which can heat up to 8000 degrees or something.
Edit because it was late night: Cones see color! Rods see detail and light. And apparently it’s red blue green. Color is super strange anyway. It doesn’t really exist unless it’s perceived.

Blue whales are estimated to produce around 20 liters of semen each time they ejaculate

Kangaroos can’t hop backwards. So if you’re ever attacked by one, just step behind him. Thanks Snapple!

Nest Level Wisdom
Yes the egg came before the chicken. As the division of sex came long before vertebrate life. However it's looking like sperm came slightly before the egg cell.
Bacteria and early multi cell lifeforms are WEIRD
David Paterson 2 years ago
"sperm came slightly before egg cell". I haven't heard that before but it does make sense. A key word is "opisthokonta", a group that includes all animals, fungi and some flagellate amoebas. The sperm is a flagellate cell. So sperm were around before the first animal.

Busy Without Breaks
When finding nectar bees swarms in random direction and when bee find the source of nectar the go back to their hive Bees communicate with other bees where the nectar is located by their special dance which indicates
1. Direction of nectar with respect to sun
2. Exact Distance of nectar from the hive
3. Time before sunset (this point is controversial as there is only one research paper available)

Buzzing With Attitude
Some insects don't have a brain, instead using their whole nervous system to think. As a result, I recently saw a video of a decapitated wasp trying to eat its own head.

Female Spotted Hyena's have a "pseudo-penis". They give birth from this. I cannot even imagine because it sounds traumatic.

Many don't survive the birth process because of the truama.

Male stoats have a penile bone. Wolverines mark their food with urine and musk to prevent other animals from stealing it. Sea cucumbers vomit their intestines.
