The king cobra is a venomous snake endemic to Asia. With an average length of 3.18 to 4 m and a maximum record of 5.85 m (19.2 ft), it is the world's longest venomous snake. Colouration of this species varies across habitats, from black with white stripes to unbroken brownish grey. The sole member of the genus Ophiophagus, it is not taxonomically a true cobra, despite its common name and some resemblance. The king cobra inhabits forests from South to Southeastern Asia where it preys chiefly on other snakes, including those of its kind. A female king cobra builds a nest to hold its eggs which will be protected throughout the incubation period.
Cobra is the common name of various snakes, most of which belong to the genus Naja.
Elapidae is a family of snakes characterized by their permanently erect fangs at the front of the mouth. Most elapids are venomous, with the exception of the genus Emydocephalus. Many members of this family exhibit a threat display of rearing upwards while spreading out a neck flap. Elapids are endemic to tropical and subtropical regions around the world, with terrestrial forms in Asia, Australia, Africa, and the Americas and marine forms in the Pacific and Indian Oceans. Members of the family have a wide range of sizes, from the 18 cm (7.1 in) white-lipped snake to the 5.85 m king cobra. Most species have neurotoxic venom that is channeled by their hollow fangs, and some may contain other toxic components in various proportions. The family includes 55 genera with some 360 species and over 170 subspecies.
Mambas are fast-moving, highly venomous snakes of the genus Dendroaspis in the family Elapidae. Four extant species are recognised currently; three of those four species are essentially arboreal and green in colour, whereas the black mamba, Dendroaspis polylepis, is largely terrestrial and generally brown or grey in colour. All are native to various regions in sub-Saharan Africa and all are feared throughout their ranges, especially the black mamba. In Africa there are many legends and stories about mambas.
Aspidelaps is a genus of venomous elapid snakes endemic to Africa. Species in the genus Aspidelaps are commonly called shield-nosed cobras, African coral snakes or coral cobras after their cobra hoods and enlarged rostral (nose) scales. However, the hood is not nearly as well developed in Aspidelaps as it is in the true cobras of the genus Naja.
The tiger snake is a large and highly venomous snake of southern Australia, including its coastal islands and Tasmania. These snakes are often observed and locally well known by their banding, black and yellow like a tiger, although the species can be highly variable in coloration and patterning. All populations are classified within the genus Notechis (Elapidae). Their diverse characteristics have been classified either as distinct species or by subspecies and regional variation.
The Caspian cobra, also called the Central Asian cobra, ladle snake, Oxus cobra, or Russian cobra, is a species of venomous snake in the family Elapidae. The species is endemic to Central Asia. Described by Karl Eichwald in 1831, it was for many years considered a subspecies of the Indian cobra until genetic analysis revealed it to be a distinct species.
Hydrophis schistosus, commonly known as the beaked sea snake, hook-nosed sea snake, common sea snake, or the Valakadeyan sea snake, is a highly venomous species of sea snake common throughout the tropical Indo-Pacific. This species is implicated in more than 50% of all bites caused by sea snakes, as well as the majority of envenomings and fatalities.
Venomous snakes are species of the suborder Serpentes that are capable of producing venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The poison is typically delivered by injection using hollow or grooved fangs, although some poisonous snakes lack well-developed fangs. Common venomous snakes include the families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine LD50, while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of poison delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake poison may have both neurotoxic and hemotoxic or cytotoxic properties. There are about 600 venomous snake species in the world.
Naja is a genus of venomous elapid snakes commonly known as cobras. Members of the genus Naja are the most widespread and the most widely recognized as "true" cobras. Various species occur in regions throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are also called "cobras", such as the king cobra and the rinkhals, but neither is a true cobra, in that they do not belong to the genus Naja, but instead each belong to monotypic genera Hemachatus and Ophiophagus.
The Mozambique spitting cobra is a highly venomous species of spitting cobra native to Africa. It is largely found in Angola, Botswana, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe.
The Chinese cobra, also called the Taiwan cobra, is a species of cobra in the family Elapidae, found mostly in southern China and a couple of neighboring nations and islands. It is one of the most prevalent venomous snakes in China and Taiwan, which has caused many snakebite incidents to humans.
The Indochinese spitting cobra also called the Thai spitting cobra, black and white spitting cobra, Siamese spitting cobra, is a species of spitting cobra found in Southeast Asia.
Goldie's tree cobra, also known commonly as the African tree cobra and as Gold's tree cobra, is a species of venomous tree cobra in the family Elapidae. The species is native to Central and Western Africa. This species is one of the two tree cobras in Africa, the other being the black tree cobra. Goldie's tree cobra is one of the most venomous snakes and creatures in Africa.
The snouted cobra, also called the banded Egyptian cobra, is a highly venomous species of cobra found in Southern Africa.
Most snakebites are caused by non-venomous snakes. Of the roughly 3,700 known species of snake found worldwide, only 15% are considered dangerous to humans. Snakes are found on every continent except Antarctica. There are two major families of venomous snakes, Elapidae and Viperidae. 325 species in 61 genera are recognized in the family Elapidae and 224 species in 22 genera are recognized in the family Viperidae, In addition, the most diverse and widely distributed snake family, the colubrids, has approximately 700 venomous species, but only five genera—boomslangs, twig snakes, keelback snakes, green snakes, and slender snakes—have caused human fatalities.
Aspidelaps lubricus, commonly known as the Cape coral snake, Cape coral cobra or Coral Shield Cobra, is a species of venomous snake in the family Elapidae. The species is endemic to southern Africa.
Philodryas olfersii is a species of venomous snake in the family Colubridae. The species is endemic to South America.
The Andaman cobra or Andaman spitting cobra is a species of cobra endemic to the Andaman Islands of India. The name of this cobra comes from the Islands itself. The species has a very potent venom, and is capable of “spitting”, although this defensive behavior is very rare and the aim is poor and not as efficient as “true spitting cobras”.
