8 Animals With Misleading Names

  • 3 of 4


5. Killer Whale.

They may be big, they may be mighty, and they may be tough, but, for the most part killer whales are not dangerous to humans… as long as they are not kept in captivity. There has never once been a documented case of a wild killer whale killing a human, and the few attacks that have occurred are incredibly rare. Even the “whale” moniker is a bit off: killer whales are actually more closely related to dolphins, not what most of us are referring to when we mean whales.

6. Guinea Pigs.

Of course, guinea pigs are not pigs at all — but they’re not from Guinea, either! This rodent is from South America, not Africa. So what’s with the confusing name? Experts aren’t sure, but there are several theories, largely having to do with the way the animal was marketed to 17th century British consumers. Here are a few possibilities: in English, the term “Guinea” has meant an exotic, far-off locale, so it could have just been a way to market a then-unknown pet. Or, it could be that the guinea pig was shipped to Europe through the African country of Guinea, losing its origin place along the way. The most common possibility, that the guinea pig is so named because the animal was once sold for a guinea coin, can’t be true, because the guinea pig’s arrival in Europe predates the guinea coin by a decade.

I hate to break it to the "owner" but this cat has adopted his friend.

Are we sure stuff grown commercially in the U. S. doesn't have the same problems?
