Have you ever heard that old adage "you can't see your heart"? If so, then know that this fully applies in the animal kingdom, since nature has gifted us with cute animals that can kill not only other animals, but even human beings!

Yeah, the animal kingdom works that way: not always what appears to be actually is. Want an example? Then see the pit bull. This dog breed has everything to be tame and a beautiful company for man, but if trained the wrong way, it becomes extremely aggressive, being able to attack and even kill any living being that puts it in danger.

In the case of the animals listed in our text, the logic holds. So how about finding out who are the cute animals that hide danger? Let's go!

Check out now who are these cute animals that can fool us with their little faces, but are dangerous if they feel a threat. So stay tuned when you come across any of them!

First on the list of cute animals that can kill is the dolphin. Well, up to him! Quite graceful and, because of that, a tourist attraction in several places, such as Cancún in Mexico, it is impossible to resist its charm – although be alert about the exploitation of the animal for tourism, which is nothing animal friendly.

However, when we talk about this animal in a tone of danger, it is, in fact, the bottlenose dolphin species. Famous for appearing in the movie Flipper, this type of dolphin is a top predator, even killing sharks just by using its snout and delivering a fatal blow to the gills or stomach of its “enemy”. Who would say no?

You've probably heard of the roadrunner, haven't you? After all, the pussy has had a cartoon to call his own on television since 1949. Created by director Chuck Jones with stories developed by writer Michael Maltese, this children's series made children's minds for a long time.

However, those who watched the cartoon must remember that the roadrunner was, in fact, the victim of a coyote, which was always creating traps to hunt him. In real life, the story is different and the roadrunner is another one of those cute animals that can kill without mercy. Extremely aggressive when hunting, you have to be very careful with it.

Considered the most dangerous fluffy dog in the world, the dingo is a subspecies of the gray wolves. As a pack hunter, it preys on larger and more dangerous animals, such as emus, the second largest land bird species in the world, and also preys on kangaroos, rabbits and even cattle.

To give you an idea, the dingo, along with his flock, is capable of killing up to 50 sheep in just one hunting night! Impressive, isn't it? But we can be calm about having to face it, since the animal lives in Australian lands, far away from our Brazil.

If you are a reader of our blog, you must have come across this one that is part of the list of cute animals that can kill: giant otter. This is because he is also considered one of the rarest animals in the world!

Also called “river wolf”, giant otter is a mustelid mammal, characteristic of the Pantanal and the Amazon River basin, in South America. Like the Dingo, this animal also hunts in packs and the group is able to face even larger animals, such as panthers, thanks to its violent technique called “tug of war”, in which the animal is stretched until the internal organs rupture.

Despite looking like the cutest-thing-in-the-world, the leopard seal, considered the second largest seal species in Antarctica, is an excellent predator and feeds on penguins, cephalopods and, amazingly!, even other seals. In other words, she is the definition of the term savage cannibalism.

Although it is the number 01 enemy of other animals in Antarctica, it is so cute and cuddly that no one expected it to pose a danger to humans, but it does. There are even reports of attacks by these animals against researchers. Fortunately, they weren't fatal, but, right, it's good to know the information to be smart in the event of finding it.

Tenth on our list of cute animals that can kill is the weasel. Existing in several species (including the black-legged weasel has also been previously on our blog as it is one of the rarest animals in the world), this kitty has an extremely aggressive behavior. So aggressive that the weasel usually lives alone, as it is dangerous even for members of the same species.

When hunting, it usually wraps around the victim's body and crushes the skull or trachea, taking a bite. Afterwards, the weasel still uses the victim's skin to make nests. It's easy? A curious fact is that, in the case of weasels, it is the mothers who guarantee the feeding of their offspring. So, after they give birth, the aggressiveness increases to be able to capture their prey and not give them a chance to escape.

Such is its cuteness, it's hard to believe that the panda is one of the cute animals that can kill, isn't it? But it's true! Obviously, we all love these cute furry ones, because they look innocent and defenseless, but the reality is different and it's better not to cross the path of an angry panda.

This is because, by invading the animal's territory, making it feel irritated, you could end up seriously injured, as we are talking about a wild animal that has characteristics very similar to that of a bear, and can reach up to 160 kg. So, here's the message: if you spot a panda, it's better to go against your instincts and get away as soon as possible!

Yes, the swan! Who sees it floating calmly in a lake, never imagine how aggressive a swan can be. Also because these animals are symbols of love and romance, since the shape of their necks, when joined in two, form a perfect heart, right?

However, if you meet someone who has ventured too close to a swan, you can be sure they will tell you that these birds have a terrible problem with aggression. For example, in 2012, a swan on a lake in Des Plaines, Illinois (USA) was able to knock over a park employee's kayak. The problem could have ended there, but it went further: the animal prevented him from swimming towards the shore, causing him to drown and die from fatigue. A huge tragedy!

The anteater is a very typical animal from Brazil and it is not uncommon to come across it on Brazilian roads, mainly in the central-west region of our country. However, if you find this lost animal out there, know that, despite looking nice and harmless, it is one of the cute animals that can kill.

You might wonder how the anteater can be a risk, since it doesn't even have teeth. The question makes sense, as long as you don't look at the animal's claws. These are your true weapon! In addition to being used for digging, this animal does not hesitate to use them to defend itself. You can be sure: these paws can do a lot of damage with just one blow.

Maybe the animal's name says it all, but just take a look at its little face. The animal looks so funny and cuddly that it makes us fall into that typical case where emotion is greater than reason. After all, the name was already warning us, wasn't it? So, yes, the Tasmanian devil is indeed dangerous, especially when someone has the bad idea of disturbing their burrows. In this case, the Tasmanian devil is capable of killing a person.

So, with the information that the Tasmanian devil is capable of killing a person, we come to our top 5 cute animals that can kill. So, do you have any idea what else is to come?

Although it is one of the biggest and strongest animals in the world, people tend to see elephants as friendly and harmless creatures. However, the truth is that humanity treats them cruelly, almost always in search of their ivory tusks or exploitation for tourism, and perhaps this is the reason for the increase in the number of fatal incidents involving men and elephants.

As we well know, elephants are extremely intelligent and, therefore, some believe that these attacks are a form of planned revenge. So when they are hunted or feel cornered, they show why they are on the list of cute animals that can kill.

Have you ever heard of the lazy loris? If not yet, then thank you for having come your time to discover it, because its rounded eyes that give the animal an extra cuteness only makes us deceive. This is because we are talking about the most venomous mammal in the world.

The lazy loris produces the venom through a gland on its arm, which is harmless to itself and which it licks to create a venomous bite. She, in turn, can provoke anaphylactic shock and other really dangerous conditions, which makes the loris compared with a poisonous snake.

Who doesn't love these aquatic animals, which can learn so many feats and look so cute? Be careful though: sea lions are big, strong carnivores that love to devour penguins. In fact, not even humans are completely safe from these animals.

With long, strong teeth, sea lions can get very aggressive if someone gets too close. In 2003, for example, 28-year-old British biologist Kirsty Brown was swimming when she was dragged and drowned more than 60 meters deep by a sea lion. Unfortunately, it did not survive the attack.

Despite being small in size, the wolverine is one of the cutest animals that can kill, as it is capable of taking down prey considerably larger than itself. Extremely aggressive, its sharp claws and strong jaws are a perfect recipe for danger, especially considering that the wolverine is very smart.

By the way, truth be told: an animal that inspired Marvel's Wolverine can't be very charismatic, can it? Yeah, maybe you don't know, but the glutton served as inspiration for the creation of this character. Even translating his name into English, you discover that wolverine and wolverine are the same thing!

To end the list of cute animals that can kill, we have the kangaroo, a typical Australian animal. For those who don't know, this animal is very good at fighting and it's not uncommon to see reports of it getting into conflict with humans. Even in 2009, a woman was beaten by a kangaroo, which was being chased by the victim's dog. The violence was such that she was taken to the hospital and underwent surgery, receiving 25 stitches to close the wounds caused by the kangaroo.

So, did you like to meet the cute animals that can kill? Surely, after this text of ours, you will be smart when you come across one of them in front of you, isn't it?
