Octopuses have three hearts. Two pump blood to the gills, and one pumps it to the rest of the body. When they swim, the heart that delivers blood to the body actually stops beating, which is why they prefer crawling!
Spiny Situation
Hedgehogs have between 5,000 and 7,000 spines on their back! Each spine lasts about a year before it falls out and a new one grows in its place. Baby hedgehogs are born with their spines just below the skin.

Mood Ring Lizards
Bearded dragons can change color based on their mood and body temperature! They darken when cold or stressed, and lighten up when warm and happy. Their 'beard' puffs out and turns black when they're showing off.
Purring Bunnies
Rabbits purr when they're happy! Unlike cats, they do it by softly grinding their teeth together. They also do 'binkies' (joyful leaps and twists in the air) when they're feeling playful.
Dolphin Name Tags
Each dolphin develops its own unique signature whistle, essentially a name! They use these to call out to specific friends. Dolphins can remember these 'names' for over 20 years.
Tongue Sniffers
Snakes smell with their tongues! They flick their forked tongue to collect chemical particles from the air, then press it into the Jacobson's organ on the roof of their mouth to 'read' the smells.
Headbutt Means Love
When your cat headbutts you, it's called 'bunting' and it means they love and trust you! They have scent glands on their forehead, and bunting is their way of marking you as 'theirs.'
Crow Detectives
Crows can recognize individual human faces for years and will teach other crows who is 'friend' or 'foe.' They've been known to bring gifts to people who feed them, from shiny buttons to earrings!

Elephants Mourn
Elephants hold funerals for their dead. They'll gently touch the bones of deceased family members with their trunks and stand vigil for hours. They've even been seen crying.
Axolotl Superpowers
Axolotls can regenerate entire limbs, their heart, spinal cord, and even parts of their brain with zero scarring! Scientists study them hoping to unlock regeneration secrets for humans.
Wombat Cube Poop
Wombats produce cube-shaped poop! Their intestines have varying elasticity that molds their droppings into cubes so they don't roll away, perfect for territorial marking on rocks and logs.
Honeybee Democracy
When honeybees need a new home, they hold a democratic vote! Scout bees dance to advertise locations, and the swarm 'votes' by joining the dance of their preferred spot until consensus is reached.
