Perhaps few people will notice the threat of stingrays until the crocodile hunter steve irwin was killed in 2006.

Don't be deceived by these watery innocent eyes. This small primate can release toxins from the elbow and is one of the only poisonous mammals in the world.

If you accidentally step on it, this small animal living in the Pacific Ocean may bite you back.

6. The golden poison dart frog-a fatal danger under the gorgeous appearance
Despite its gorgeous appearance, it is one of the most poisonous animals in the world.

13, hippo-protect territory and punish intruders
Simple and honest hippo is a lovely image in countless cartoon stories: cute little ears, interesting round eyes, sparkling eyes ... everything seems so gentle.

Although it weighs 8000 pounds, it can catch up with humans at a speed of 20 miles per hour. The structure of the lower jaw allows them to clamp the weight of 6000 pounds, and the canine teeth with the size of 10 inch will make him the object you stay away from.
Hippos are herbivores, so they don't often eat people, but this doesn't prevent them from "biting twice" when they are in a bad mood.
14, swan-despair with you when you are in a hurry.
How beautiful and elegant swans are in my mind, but they are the craziest parents and can fight to the end to protect their children.
Many birds will instinctively protect their young when they meet natural enemies, but many will give up when they are weak. But swans don't. They will fight to the death!

16, elephant-will attack for no reason.
Elephants are wonderful animals. They are friendly, docile and accessible. People even found that elephants shed tears when their loved ones died. But just like "no one is perfect", in some cases, elephants will go crazy, and their size and weight are the absolute advantages that overwhelm their opponents.
In fact, every animal has a violent side. As the saying goes, "A dog jumps over the wall and a rabbit bites." But if the elephant is in a hurry, it will stick out its huge feet or fangs, which will directly lead to the offender.
Many animal trainers or keepers in the zoo unfortunately died at the hands of these seemingly friendly elephants, even though the artificially raised elephants were not much better. Moreover, studies have shown that because of the exuberant secretion of androgen, elephants in mating period will attack without reason and restraint.
