where does this thinking come from, ive seen it too many times to be a fluke. Is it at the same places creationism is taught? (Not trying to be funny or rude, I just really wonder what the source of this is)

This is very much the case. Wikipedia is a decent guide to this sort of thing and given that it says "The great white shark (Carcharodon carcharias), also known as the white shark, white pointer, or simply great white" these should all be accepted.

Can you please remove the sting ray question because the whole point of Steve Irwin's show when he died was to prove they're not a threat. They have killed almost noone ever. He accidentally stepped on the stingray I think provoking the sting to happen. He died from a freak and incredibly unlikely accident and it kind of insults his memory to put stingrays on a list of deadly animals. This is coming from a true blue Australian who has swum with stingrays.

I am against people who, to make a television program or to promote themselves, handle and intervene with animals. To handle wild creatures and to have them in zoos and then handle them for the amusement of audiences is to my mind the very opposite of what we as a human race should do. The less interaction that wild animals have with humans the better for them.

Clearly, zoo promotional campaigns are doing a good job miseducating the public. I don't know where to begin with the irony of defending zoos by calling actual conservation best-practices outdated.

Effective wildlife conservation means conserving habitat and sanctuaries, not keeping wildlife in prisons in perpetuity. People can learn to support conservation efforts in ways that don't involve animal objectification and cruelty. Backyard zoos and breeding programs do little to nothing to preserve species. (As a side note, providing rehab and care for injured/permanently disabled wildlife is different from permanently interned animals on display.)

There are lots of online articles and data articulating how zoos do more harm than good -- I recommend checking them out if you're on the fence :)

(I'm with Malbaby, if it wasn't obvious :)

If an animal isn't a threat but kills you if you provoke it the wrong way... it's a threat. That line of reasoning is like saying a gorilla or a knife isn't a threat, because if you don't go near it it won't hurt you. It's true, but only in the least helpful way imaginable.

Understood, though there have been a handful of fatal stingray accidents, Irwin's just happens to be the most famous. And stingrays have defenses that must be respected, even if they rarely prove fatal. By numbers, they have probably killed more people than piranha, but this quiz is about perception, not numbers anyway.

I don't think a quiz like this needs to particularly endorse or condemn Irwin the man, and I don't think the question really does. It remains possible for the reader to decide if his actions were laudable or not, but the quiz isn't misleading.

Ok, couple things: first off, I was confused about whether you meant the deadliest, 2nd-deadliest, and 3rd-deadliest snake in the US, or the deadliest animals overall. I kept trying to type coral snake, diamondback rattler, etc. Second, "the most dangerous game" is a misleading clue. I thought you were asking us to name the most dangerous game animal, so I kept trying moose, elk, bison, etc.

Poison dart frogs are not venomous. Venom requires a delivery system such as fangs. They secret toxins in their skin. So that makes them poisonous. If you want to avoid the word "poisonous" you could use "toxic" as a replacement.

Went on a "swimming with dolphins" trip in a tributary of the Amazon once, but never saw any. The next day though we went "fishing for piranhas" and caught a bunch of them very easily.

I was expecting it to be in a different river, but no... same river, same spot, same time of day. I asked the guide whether it might have been a bit dangerous swimming in a river full of piranhas. He said, "No, they only eat you if they are hungry."

Elephants do not get drunk and kill people:

"There are YouTube videos claiming to show drunk elephants destroying villages after eating fermented marula fruit.

But, here's the thing: According to the BBC, elephants are so huge that it would take massive amounts of marula fruit to get them drunk. In order to actually become inebriated, an elephant would have to eat 400% more fruit than it normally does, without drinking any water.

While they may be way too big to get wasted, a 1984 study in the Bulletin of the Psychonomic Society found that elephants could eat enough fruit to become slightly "buzzed." In that state they became lazier when eating and bathing – not exactly rampaging behavior."

get Pit Bulls off this list, it is irresponsible, disingenuous, and frankly pathetic to include them. The rest of these animals are inherently deadly, a pitbull is only violent when a dirtbag human trains them to be that way. Look at their history, they're some of the most gentle breeds out there - used to watch over children, protect families, etc. You're enforcing negative stereotypes, which leads to dogs being put to sleep because no one will adopt them. This is disgusting.

66% of fatal dog bites in the U.S. are caused by pit bulls. This is not a "negative stereotype". It's a fact. And while I agree that it is the owners of pit bulls who are to blame, there is something else which you haven't considered. When pit bulls bite, they are more likely to kill their victim. This is a trait inherent to the breed, which is one reason that pit bulls are banned in England and Wales. I'm sorry this makes you uncomfortable. It's sad when unwanted pets are killed. It's much worse when a child is killed by a dog.

It is absolutely not a fact that 66% of fatal dog bites in the US are from pit bulls. This is a stat that's been spread around the news so much everyone just "knows" it, but it's just not true and has been debunked a million times (most thoroughly in Bronwen Dickey's book Pit Bull: The Battle Over an American Icon.

Besides it just being unlikely on its face, do a little research into how data on fatal dog bites are collected, including breed-specific data (almost always just reported by a witness), and how bad people are at identifying breeds.

This "inherent in the breed" thing is just stupid and has, over the centuries, been used to describe German shepherd dogs, Cuban bloodhounds and even the "Spitz", a breed group that includes Pomeranians.

Yes, it's a breed trait. Pit bulls are bred to fight. Bloodhounds are bred to smell. Pointers are bred to point.

Dogs are not blank slates, they have extremely strong breed traits as anyone who has ever owned a dog knows.

Don't let your love of dogs overrule common sense and never let your children anywhere near a pit bull. The stories of people (often children) being literally torn apart by their beloved pit bull pets are as common as they are tragic.

Here's one from just yesterday.

"This was the same dog who was side by side with my baby every single day."

This is a common refrain of people whose children are killed by pit bulls. One moment they are loving, happy. Then they get triggered by something and become extremely aggressive.
