What can cats see that humans can't? 🐱 Cats can see UV light, which is invisible to humans. Cats can do a lot of things their human friends can’t: They can purr, sleep all day without consequence, and jump up to six times their own height in a single leap. But perhaps most impressive of all is their ability to see ultraviolet light thanks to UV-transparent lenses in their eyes that allow UV light to reach their retinas. This will come as little surprise to anyone who’s ever noticed their cat staring at seemingly nothing for minutes at a time, but it’s a fascinating insight into how our feline friends view the world all the same. In fact, their UV vision actually allows them to see their prey’s urine trail while hunting and distinguish between their prey and a similarly colored background. This ability may not help your housecat in any practical ways on a daily basis, as being fed from a can doesn’t require much in the way of hunting, but it’s still a cool evolutionary trick. And cats aren’t the only animals with this ability. Bees, birds, reindeer, and mice have this enhanced vision as well, though for some of them it comes with the trade-off of not being able to see the color red. Humans have kept cats as pets for at least 9,500 years. When we think of cats in the ancient world, Egypt tends to come to mind first. Egyptians considered felines sacred and some even mummified their pets, but they weren’t the first to hold cats in such high regard. There’s evidence to suggest they were beaten to the punch by at least 4,000 years: A grave in Cyprus dating back some 9,500 years contained the remains of a human and cat alongside decorative objects such as seashells and polished stones. Cats aren’t native to the island, meaning they must have been brought there by humans — perhaps “on a kind of Noah’s ark,” as archaeologist Melinda Zeder told National Geographic, theorizing that a number of non-native animals were transported to Cyprus. #Animals #Cats

Killer whales sometimes hunt moose. There’s a reason orcas are better known as killer whales. They’re fierce predators, and they don’t always keep to the water in search of prey — in fact, they’ve even been known to hunt moose. This happens when a member of the largest deer species (yes, moose are deer) wades into the water, either in search of food or to elude land-based predators, and finds itself in the unfortunate position of being near an orca, which will eat pretty much anything. Such occurrences have been known to happen in the Pacific Northwest and Alaska, with one recorded incident resulting in the deaths of two moose. Orcas are thought to have received their nickname centuries ago, perhaps from a mistranslation. The theory posits that Basque fisherman observed them killing other whales and referred to them as “whale killers,” which became “killer whales” when translated to English. Their diet depends largely on where they live, but different ecotypes feed on everything from fish and seals to sharks and squid, with the occasional moose thrown in. No one knows why orcas keep attacking yachts. If you’ve read about killer whales in the last few years, it’s probably because they keep sinking yachts. There have been incidents in Cape Finisterre as well as the Strait of Gibraltar, with at least 500 orcas encountering boats since 2020. (Most of these go no further than the whales merely approaching the vessels, perhaps out of curiosity, but a number of them have resulted in sunken boats.) Scientists remain unsure about the whales’ motivations. Some think they’re merely having fun or even participating in a fad, which is apparently something killer whales do — for instance, one pod spent the summer of 1987 wearing dead salmon on their heads. Others believe it’s because they’ve had negative experiences with boats in the past, including losing members of their species to the vessels. Whatever the case, the creatures don’t seem to have personal beef with the humans onboard; there have been zero recorded cases of an orca killing a human in the wild. #Animals #KillerWhales
