Being aggressive isn't so bad. As in nature, and in fiction, such creatures have many scars to prove their cockiness. But this attracts numerous women to them, who subconsciously want to be with an energetic and strong male.
There are creatures in nature that cannot be suspected of being aggressive. The danger can come not only from lions and sharks, but also from other creatures.
Koala. This Australian bear is considered to be lazy and clumsy. The koala has small eyes, huge ears. With all its appearance, the animal more resembles not an aggressor, but a large plush toy. Koala just wants to hug. In fact, you shouldn't approach this bear without a reliable set of protective clothing. The fact is that the whole body of this cute animal is teeming with chlamydia. In recent years, the koala population has been prone to outbreaks of sexually transmitted diseases. Scientists believe that this could lead to the complete extinction of the species within 30 years. So that the species does not become extinct, he needs to have sex, but it is he who becomes the cause of the spread of infection, and therefore increased mortality.
Hercules beetle. This insect looks very unusual with its large horns on its head. Meanwhile, this is one of the largest beetles on the planet, males reach a length of 15 centimeters. But besides the horns, there are also considerable wings! The amazing thing is that this creature can be considered one of the most powerful on the planet, if you take into account the ratio to size. The Hercules beetle got its name for a reason. It is capable of lifting 850 times its own mass. For a person, this is equivalent to lifting 70 tons of cargo at once. So the beetle earned its name in full. And he uses the horns to prove his right to access the female in a duel with a competitor. The enemy is raised with this weapon and dropped to the ground. But females do not need such a weapon, they are generally deprived of horns.
Hippopotamus. This overweight herbivore loves to splash in water. According to Madagascar, hippos love listening to R @ B. It would seem that these creatures are cute and friendly. However, they are actually insane and aggressive killing machines. In addition, they are extremely negative about humanity. The hippopotamus is one of the largest land animals. This makes him extremely dangerous, because he is not only aggressive, but also not afraid of a person. Any slightest reason provokes the hippopotamus to attack. This natural weapon of death is believed to be responsible for the majority of human deaths in Africa from animals. It is the hippos that are the real danger, not the lions! And it will be a mistake to think that it will be easy to hide from the clumsy beast. In a chase state, the hippopotamus can reach speeds of 25 km / h.
Wombat. These herbivores that live in Australia look like bears. It is no coincidence that they are mistaken for distant relatives of koalas. The animal looks as if it constantly eats cupcakes and rubs against something with its belly. To imagine a wombat, you must mentally try to cross a puppy and a teddy bear. Animals weigh from 20 to 45 kilograms, and in length usually reach 70-120 centimeters. But these "harmless" animals, digging long holes for themselves, also hunt dingo dogs and Tasmanian devils. But this is a rather significant fact. The fluffy animal lures predators by diving into its long tunnel, leaving it open to intruders. When the hunters push their heads into the hole, the wombat begins to beat them with their feet. The back of the wombat is reliably protected by cartilage, bones and skin. Sharp claws turn the hunter's brain into a bloody mess. The wombat in its hole also dangerously hits its head or tries to pinch and strangle the predator with its firm bottom.
Nutria. For those who have a poor idea of what nutria is, we can also mention another name for this animal - river rat. This large rodent, originally from South America, was brought to the United States and Europe at one time. Nutria is famous not only for eating harmful locusts and for its valuable fur. This is a real machine that seeks to destroy the Earth, devouring everything in its path. Hordes of nutria result in huge losses every year. For example, in Maryland, it was these rats that destroyed more than 3 thousand hectares of swamps. As a result, the state caught on and adopted a multimillion-dollar program to eliminate the consequences of this disaster. And in 2005, Louisiana even appointed a reward for the destruction of nutria, putting them on a par with dangerous criminals. The problem is aggravated by the high fertility of this rat.
Mantis shrimp. The bright color of this creature makes you think that it is a narcotic hallucination. Meanwhile, this is a creation of nature. Interestingly, technically, a praying mantis shrimp is not actually a shrimp. It is a carnivorous crustacean from the family of stomatopods. Some people even try to place them in their tanks, but this must be done with extreme caution. The fact is that Mantis is a very aggressive creature. In its natural environment, it carefully observes with the help of its keen eyesight its prey, rapidly attacking it, grabbing it with its second pair of paws. Lightning injections are accompanied by flashes of light and heat, while the impact is carried out at a speed of up to 75 km / h. Few people decide to settle a praying mantis shrimp in a common aquarium. After all, she immediately begins to hunt her neighbors. Mantis waits for a long time, accumulating energy in himself in order to literally shoot an attack that is deadly for prey at the right moment. It should also be said that simple glass for a mantis shrimp aquarium will not work, you need acrylic. After all, the blow of an adult is tantamount to being hit by a 22 caliber bullet.
Hummingbird. This adorable tiny bird, it would seem, has always dreamed of becoming a bee. The hummingbird not only feeds on nectar, but also buzzes around the flower, often flapping its small wings. And the elongated beak of the small bird is very reminiscent of the sting of the famous striped insect. Isn't that lovely? And the hummingbird flies very unusual. There are about 90 flaps of the wings per second. This allows the birds to literally hover in the air and even fly backwards. But that doesn't make them dangerous. The fact is that this genus is constantly on the verge of starvation. The bird's heart beats 200 times faster than a human. This also suggests that hummingbirds have an extremely high metabolic rate. She needs constant feeding, otherwise she will simply die. The main food for hummingbirds is not nectar at all, but small insects that live on flowers. As a result, the bird is the most insatiable on Earth. In just 16 hours of its life, a hummingbird can drink 120 times of water and eat food more than it weighs itself.
Pacific salmon. For most of us, this fish is just delicious food on the table. Pacific salmon is a popular dish made with fried mushrooms and eggplant. Speaking about this amazing fish, it is worth asking the question, what are we ready for for having sex? To lay eggs, Pacific salmon, for the first time in their life, go into fresh water, an unusual environment for themselves. Then the fish stops eating altogether. The stomach disintegrates, making room for future offspring. Life continues due to the accumulated fat in the tissues. Then the salmon goes upstream, hiding from bears and fishermen. The fish goes to the very place where they were born. Moreover, they have neither a map, nor a GPS, nor a complex nervous system. There the salmon begins to breed until it finally dies. We can say that this is a real aggressor in relation to himself.
Cassowaries. This bird looks like a transvestite ostrich. Cassowaries cannot fly. They are the largest birds in Australia and the second largest in the world after ostriches. But few people know that bright color does not prevent cassowaries from being the most dangerous birds on the planet. It may not be a hawk or an eagle, but cassowaries are the real ninja in the bird world. In the wild, you can pass them by and not even notice. And a dangerous creature will show itself only when it decides to attack. One should beware of its extremely sharp claws. Cassowaries also have powerful legs. With this weapon, the bird can gut its prey with just one blow. Plus, horned cassowaries are quite aggressive, so the best thing to do when you see her is to lie down. It is hoped that she will quickly lose interest in the immovable person. There is no point in running away from cassowaries, because they can run at a speed of 75 km / h. It is worth noting that these birds also know how and love to swim.
Immortal jellyfish. The name of these creatures sounds a little ironic. And these sea creatures with diameters of 4-5 millimeters look quite common. But astonished scientists argue that these jellyfish can really live forever. All other jellyfish die after participating in the reproductive cycle, but the Turritopsis Nutricula species returns to an immature form after mating. This enables them to then spawn new colonies of their own. There are simply no such creatures in an animal. The cells in jellyfish organisms can transform from one species to another. The creatures themselves can thus exist permanently until they are eaten or killed. Imagine if we could suddenly turn into our pregnant mother and give birth to three clones of ourselves at once! Scientists believe that such abilities of jellyfish may give them the opportunity to change the environment of the world's oceans under favorable conditions for them. Immortal jellyfish are gradually advancing. From the Caribbean, they gradually spread to other regions.
