Karl G. asks: Why do we call an elephant’s nose a trunk? It’s not clear who first tagged the elephant’s snout with the name “trunk,” but it seems to have happened sometime in the late 16th century. The first documented instance appears in the 1589 work by Richard Hakluyt, Principal Navigations: “The Elephant . . . With water fils his […]

At only a few inches long and with no distinguishing external physical features to speak of, Scutisorex somereni, better known as the Hero or Armoured Shrew, is seemingly an unremarkable creature.

It is surely the stuff of science fiction: An extraordinary being arrives on Earth that can withstand a tortuous array of conditions: boiling, freezing, tremendous atmospheric pressure, near total dehydration, and exposure to massive amounts of ionizing radiation. While many joke that “cockroaches would be the only thing to survive an extreme global nuclear war”, in fact, cockroaches would not. […]

Karen A. asks: How prevalent is homosexuality in animals? Are there any animals besides humans that have members that are exclusively homosexual? While it is sometimes claimed that only humans engage in bisexual or homosexual relationships, this is far from the truth and the practice is actually quite common in the animal kingdom. For example, nearly 10% of male sheep […]

Piot R. asks: Where do mosquitoes disappear to during the daytime? Mosquitoes are the bane of anyone who steps outside during the hours around dusk and dawn. If not caught in time, the creatures take a drink of blood, and then leave behind an itchy bump, and maybe a disease or two. But very rarely do the insects come out […]

Ladybugs, sometimes known as Ladybirds and less commonly Lady Beetles, are a rarity in the insect world in that they’re one of the few creepy crawly insects we as a species don’t actively dislike, due to their habit of eating the things that destroy our crops. But just how did this little insect get such a strange name? To start, […]

Prized since ancient times for its alluring fragrance, today musk can mean any of a number of substances used to scent perfumes. However, while in our modern era most musk is synthetically produced, when it first came on the scene, musk was only found in a scrotum-like sac on the bellies of male musk deer. Musk deer are found throughout […]

Bon-hwa S. asks: Worms drown in the water, so how do fish know they are food? Is the reason they like them just the movement? Thanks! Worms, or more specifically earthworms which are by far what most people mean when they use the term “worms” in the fishing scenario, don’t live in water. In fact, the reason you see so many on […]

Jim asks: Do non-human animals ever get sunburned? Why don’t things like snakes and other cold blooded animals seem to get burned even though they lay in the sun all day? Without a protective coating of feathers, fur or scales, pretty much any animal with exposed skin can get a sunburn; luckily, most animals have adapted methods of avoiding the […]

Few things in childhood are more traumatising than waking up one morning to find your beloved pet fish, Michael Scofield, floating upside down in his tank (true story); his tiny fishy light cruelly extinguished before his time. But why do they float upside down when they decide it’s time to take a ride on the porcelain express? The answer to […]

Brandi N asks: How do other primates deal with the umbilical cord and placenta when the baby is born when they don’t have any sort of medical help to make sure everything’s handled right? Other than certain modern humans, some marine mammals (like whales and dolphins), chimpanzees and a few domesticated animals, mammal mothers typically eat the afterbirth. While most […]

Ryan K. asks: Given that they probably need to move their fins constantly to stay in place, do fish ever sleep? Less like sleep and more like suspended animation, most fish species do spend some time resting. And like us, if they don’t put in enough downtime, they try to make up for it later. Sleep has a simple definition […]

Gerry D. asks: Why do nats swarm in a ball in the air? A common sight in the spring and summer, the seemingly unprofitable and pointless habit of gnats to hover in a cloud is, in fact, the single most productive thing they’ll ever do with their short lives. Although there are a wide variety of non-biting, but eminently annoying, […]

Jim R. asks: Is it true that the word jumbo came from the name of an elephant?

While this is certainly a nice story, the truth is a little more complicated. First […]

Unless you didn’t quite get enough info from the title- yes, it is entirely possible for a chicken to lay an egg that contains another fully developed egg, what we now officially dub an Xzibit Egg. A wonderfully bizarre Matryoshka doll made of protein and disgusting (when you think about it) deliciousness. As you may or may not know, a […]

Considering how most dogs in the Western world these days are treated as a member of the family, it’s often easy to forget that the vast majority of our furry friends up until very recently were bred for a specific purpose. Perhaps no dog was bred for a more specific purpose than the now extinct, turnspit. The turnspit was so named […]
