Top 10 Most dangerous animals in the World
Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). All animals aremotile, meaning they can move spontaneously and independently, at some point in their lives. Their body planeventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance.
The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a large species of lizard found in the Indonesianislands of Komodo, Rinca, Flores, Gili Motang, and Padar. A member of the monitor lizard family Varanidae, it is the largest living species of lizard, growing to a maximum length of 3 metres (10 ft) in rare cases and weighing up to approximately 70 kilograms.
9.Tse Tse Fly
Tsetse , sometimes spelled tzetze and also known as tik-tik flies, are large biting flies that inhabit much of mid-continental Africa between the Sahara and the Kalahari deserts. They live by feeding on the blood of vertebrateanimals and are the primary African biological vectors of trypanosomes, which cause human sleeping sickness and animal trypanosomiasis, also known as nagana. Tsetse include all the species in the genus Glossina, which are generally placed in their own family, Glossinidae.
The leopard (Panthera pardus) is one of the five “big cats” in the genus Panthera. It is a member of the Felidae family with a wide range in regions of sub-Saharan Africa, West Asia, the Middle East, South and Southeast Asia to Siberia. Fossil records found in Italy suggest that in the Pleistocene it ranged as far as Europe.
Carpet Viper is a genus of venomous vipers found in the dry regions of Africa, the Middle East, Pakistan, India, and Sri Lanka. They have a characteristic threat display, rubbing sections of their body together to produce a “sizzling” warning sound. The name Echis is a Greek word for “viper.” Their common name is “saw-scaled vipers” and they include some of the species responsible for causing the most snakebite cases and deaths in the world. Eight species are currently recognized.
6.Brazilian Wandering Spider
Phoneutria, commonly known as Brazilian wandering spiders, armed spiders (“armadeiras”, as they are known in Brazilian Portuguese), or banana spiders (a name shared with several others), are a genus of aggressive and venomous spiders of potential medical significance to humans. They are mainly found in tropical South America, with one species in Central America. These spiders are members of the family Ctenidae of wandering spiders.
5.Blue Ringed Octopus
The blue-ringed octopuses (genus Hapalochlaena) are three (or perhaps four) octopus species that live in tide pools and coral reefsin the Pacific and Indian Oceans, from Japan to Australia. Their primary habitat is around southern New South Wales, South Australia, and northern Western Australia. They are recognized as one of the world’s most venomous marine animals. Despite their small size, 12 to 20 cm (5 to 8 in), and relatively docile nature, they are dangerous to humans if provoked and handled, because their venom is powerful enough to kill humans.
The hippopotamus (Hippopotamus amphibius), or hippo, is a large, mostly herbivorous mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis orHexaprotodon liberiensis). The name comes from the ancient Greek for “river horse”. After the elephant andrhinoceros, the common hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the Hippopotamidae arecetaceans (whales, porpoises, etc.) from which they diverged about. The common ancestor of whales and hippos split from other even-toed ungulates around . The earliest known hippopotamus fossils, belonging to thegenus Kenyapotamus in Africa, date to around .
The saltwater crocodile (Crocodylus porosus) is also widely known by the common names, estuarine or Indo-Pacific crocodile, more rarely or informally referred to as the saltie, marine or sea-going crocodile. This species is the largest of all living reptiles, as well as the largest terrestrial and riparian predator in the world. The males of this species can reach sizes up to 6.3 m (20.7 ft) and weigh up to 1,360 kg (3,000 lb). However, an adult male saltwater crocodile is generally between 4.3 and 5.2 m (14 and 17 ft) in length and weighs 400 to 1,000 kg (880–2,200 lb), rarely growing larger. Females are much smaller and often do not surpass 3 m (9.8 ft). As its name implies, this species of crocodile can live in salt water, but usually resides in mangrove swamps, estuaries, deltas, lagoons, and lower stretches of rivers. They have the broadest distribution of any modern crocodile, ranging from the eastern coast of India, throughout most of Southeast Asia, and northern Australia.
African elephants are elephants of the genus Loxodonta (from the Greek words loxo (oblique sided) and donta (tooth)). The genus consists of two extant species: the African bush elephant and the smaller African forest elephant. Loxodonta is one of two existing genera of the family, Elephantidae. Fossil remains of Loxodonta have been found only in Africa, in strata as old as the middle Pliocene.
Mosquitoes are small, midge-like flies which comprise the family Culicidae. Females of most species are ectoparasites, whose tube-like mouthparts (called a proboscis) pierce the hosts’ skin to consume blood. The word “mosquito” (formed by mosca and diminutive ito) is Spanish for “little fly”. Thousands of species feed on the blood of various kinds of hosts, mainly vertebrates, including mammals, birds,reptiles, amphibians, and even some kinds of fish. Some mosquitoes also attack invertebrates, mainly arthropods. Though the loss of blood is seldom of any importance to the victim, the saliva of the mosquito often causes an irritating rash that is a serious nuisance. Much more serious though, are the roles of many species of mosquitoes as vectors of diseases. In passing from host to host, some transmit extremely harmful infections such as malaria, yellow fever, west Nile virus, dengue fever, filariasis, and other arboviruses, rendering it the deadliest animal family in the world.
