12 of the most aggressive creatures on Earth

6686

Despite the fact that most organisms on Earth live peacefully and in perfect harmony with Mother Nature, there are some creatures that are absolute predators and are constantly competing with other forms of life. According to most dictionaries, aggressive species is a plant or animal that is not native to a specific location. In other words, introduced species that tends to spread and can cause damage to the environment, human economy and human health. Some of these aggressive beings caused the extinction of entire species and has caused irreparable damage to the surrounding ecosystem. With that said, don’t think they are very scary or dangerous. Some of these aggressive creatures live as Pets because they are cute or even exotic. However, the sad reality is that with the introduction of their natural habitat they get out of control and begin to behave as predators.

12. Nile perch

The Nile perch is a large freshwater fish that can grow up to 200 kg and can reach two meters in length. It was introduced into Lake Victoria in 1954, which contributed to the disappearance of more than two hundred local species of fish through predation and competition for food.

11. Cats

Believe it or not, domesticated cat, is one of the most aggressive creatures on Earth. Given the extent to which cats are valued as Pets, it is not surprising that they are found in all parts of the world. Known predators, cats threaten bird life and other fauna, especially on Islands where native species have evolved in relative isolation from predators.

10. Snail is a cannibal

Snail cannibal appeared on the Islands of the Indian and Pacific oceans in 1950 as a biological control agent for the giant African snail. As its name implies, this snail will eat everything that gets in her way, even her own kind.

9. Japanese starfish

Originally found in far North Pacific waters and areas surrounding Japan, Russia, Northern China and Korea, the Northern Pacific sea star has successfully invaded the southern coast of Australia, and has the potential to move far to the North of Sydney. Starfish eat a wide range of production and has the potential for environmental and economic harm wherever it may be.

8. Crazy dark-red ant

Crazy dark-red ants have invaded the natural ecosystem and caused environmental damage from Hawaii to the Seychelles and Zanzibar. On Christmas island in the Indian ocean they formed multikeralash super colony. They also destroy the population of the red land crab (Gecarcoidea natalis). Crazy ants also prey or interfering with the reproduction of many arthropods, reptiles, birds and mammals.

7. Ordinary mosquito mosquito

Scientifically known Anopheles quadrimaculatus is the mosquito, which is responsible for most cases of malaria in North America. They usually are in places with rich aquatic vegetation such as rice fields and adjacent irrigation ditches, freshwater marshes and rich vegetation, edges of lakes, ponds and reservoirs.

6. The Asian tiger mosquito

The Asian tiger mosquito is associated with transmission of many human diseases, including dengue fever, West Nile virus, and Japanese encephalitis.

5. Burmese Python

Burmese pythons could be popular Pets due to its appealing coloured pattern, known obedience and charm (for some, anyway). As predators, however, Burmese pythons pose a threat to wild animals of South Florida, which are under threat of extinction. Their rapid and widespread invasion is facilitated by aspects of their natural history, including their use of a variety of habitats, broad dietary preferences, long lifespan, high reproductive performance and the ability to travel long distances.

4. Gray squirrel

Gray squirrel may be cute, but it is an aggressive mammal in British Columbia, which is estimated Invasive Species Specialist Group (ISSG) as one of the 100 most aggressive species in the world. This small mammal has a large environmental impact, often causing disease (parapoxvirus), and is responsible for displacement of native birds by eating their eggs and Chicks.

3. The European rabbit

The wild European rabbit is one of the most widespread and large mammals in Australia. It causes serious damage to environment and agriculture. It is difficult to control the European rabbit due to issues of social security and harvest, and because local and introduced predators feed on wild rabbits in many parts of Australia. Invader and victim at the same time? This is too much.

2. The black rat

A native of the Indian subcontinent, the so-called black rat has now spread throughout the world. It is widely distributed in forests and woodlands, and can live in buildings. The black rat will eat, and damage almost any edible thing. To understand how aggressive this creature, keep in mind that it is most often identificireba with a catastrophic decline in birds on the Islands.
