Scientists sometimes call Polar Bears "Lipovores" because their main source of calories comes from marine fat/blubber. They assimilate the majority of it directly into their own body fat & don’t digest carbohydrates or proteins as well as Brown Bears do.

The white-tipped sicklebill uses its extremely decurved bill to reach inside sharply curved flowers, allowing it to drink nectar other nectarivores cannot reach. It is also a ‘trapliner’ — repeating the same foraging circuits, visiting favourite flowers along its particular route.

Emperor penguins have officially been declared at risk of extinction by the IUCN. This is because the ice they rely on to hatch and raise their chicks is melting, leading to colony collapse.

Bare-throated bellbird. The male has one of the loudest calls of any bird—a sharp sound like that of a hammer striking an anvil or a bell, and It might takes a long time for young males to learn & perfect the call.

Fairy Bees: these tiny bees can measure less than 2mm long; the photo on top shows a fairy bee standing on a quarter, while the photo on the bottom shows a fairy bee next to a carpenter bee.

Australian Resin-Pot Bees: these solitary bees build nesting capsules out of resin, often suspending the capsules from twigs and tree bark.

In 70% of bird species, female birds sing, including alongside males in mating rituals. Males and females sometimes make completely different sounds, making it possible to distinguish between them just by listening. However, despite this, only.03% of archived sounds are labelled as female.

Mirror-Ball Spiders: these spiders are covered in shimmering, mirror-like panels that can shrink or expand; the panels are produced by a digestive secretion known as guanine, which seeps into the lining of the spider's gut and forms crystalline structures just beneath the surface of the abdomen.

Bee Hummingbirds: these are the smallest birds in the world, with males measuring up to 5.5cm long and weighing an average of just 1.95 grams, which is less than the weight of a dime.

The saola — often called the "Asian unicorn" — is endemic to the Annamite Mountains of Laos and Vietnam. Discovered by science in 1992, it has never been directly observed alive by researchers in the wild and may number fewer than 100 individuals.

The star-nosed mole is the fastest eater on Earth. It hunts by slamming its nose against the soil up to 12 times a second. When it finds prey, it can identify and eat it in about 120 milliseconds, faster than the human eye can even process the motion.

The Nova Scotia duck tolling retriever is one of four native Canadian dog breeds. They help hunt ducks by playing and fetching sticks at the water's edge while wagging their tails. When the ducks come close to see what's going on, hunters catch the ducks.

Chimpanzees may get the equivalent of one or two drinks worth of alcohol when they eat fermented fruit as part of their natural browsing.

Hedgehogs do something called "self-anointing." When they encounter a new or strong smell (a strange food, another animal's scent, even a strong-smelling plant) they'll chew it up, work it into a frothy saliva, and then twist around to spread that foam all over their own spines with their tongue.

Danionella cerebrum was first identified as its own species in 2021. It has transparent skin and is missing the top half of its skull, making it ideal for scientists wanting to study how brains work.

Bison are being reintroduced into Cuenca Los Ojos, a nature preserve along the US-Mexico border. There, they will be key to restoring a natural landscape. Their dung and fur carry grass seeds, their grazing creates habitats for birds, and their bodies provide nutrients for scavengers and the soil.
