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 varying proportions. The family includes 55 genera with around 360 species and over 170 subspecies.
Bungarus is a genus of venomous snakes in the family Elapidae. The genus is native to Asia. Often found on the floor of tropical forests in South Asia, Southeast Asia and Southern China, they are medium-sized, highly venomous snakes with a total length typically not exceeding 2 metres. These are nocturnal ophiophagious predators which prey primarily on other snakes at night, occasionally taking lizards, amphibians and rodents. Most species are with banded patterns acting as a warning sign to their predators. Despite being considered as generally docile and timid, kraits are capable of delivering highly potent neurotoxic venom which is medically significant with potential lethality to humans. The genus currently holds 18 species and 5 subspecies.
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 colouration 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 common krait, also known as Bengal krait, is a species of extremely venomous snakes of the genus Bungarus in the Elapidae family, native to the Indian subcontinent. It is one of the Big Four Indian snakes that inflict the most snakebites on humans in India, Pakistan and Bangladesh.
The banded krait is an extremely venomous species of elapids endemic to Asia, from Indian Subcontinent through Southeast Asia to Southern China. With a maximum length exceeding 2 m, it is the longest krait with a distinguishable gold and black pattern. While this species is generally considered timid and docile, resembling other members of the genus, its venom is highly neurotoxic which is potentially lethal to humans. Although toxicity of the banded krait based upon murine LD50 experiments is lower than that of many other kraits, its venom yield is the highest due to its size.
Bungarus bungaroides, the northeastern hill krait, is a venomous species of elapid snake.
The lesser black krait is a species of venomous elapid snake found in India, Bangladesh, and Nepal. The specific epithet is after Latin lividus, meaning “bluish metal-colored” or “lead-colored”, referring to the snake's coloration.
The greater black krait or black krait, is a species of krait, a venomous snake in the genus Bungarus of the family Elapidae. The species is endemic to South Asia.
The Caspian cobra, also called the Central Asian cobra or Russian cobra, is a species of highly venomous snake in the family Elapidae. The species is endemic to Central Asia. First described by Karl Eichwald, a German physician, in 1831, it was for many years considered to be a subspecies of the Naja naja until genetic analysis revealed it to be a distinct species.
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 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, which has caused many snakebite incidents to humans.
The many-banded krait, also known as the Taiwanese krait or the Chinese krait, is a highly venomous species of elapid snake found in much of central and southern China and Southeast Asia. The species was first described by the scientist Edward Blyth in 1861. Averaging 1 to 1.5 m in length, it is a black or bluish-black snake with many white bands across its body. The many-banded krait mostly inhabits marshy areas throughout its geographical distribution, though it does occur in other habitat types.
Calliophis bivirgatus is a species of snake in the family Elapidae known commonly as the blue coral snake or blue Malayan coral snake. It is native to Southeast Asia.
The red-headed krait is a large highly venomous elapid snake with dramatic coloration. The red-headed krait can grow to a length of up to 2.1 metres (7 ft). It lives in lowland rain forest, including those on islands, but it is considered uncommon. It feeds primarily on specific snakes, probably semiaquatic and fossorial snakes. In Southeast Asia, the red-headed krait occurs in Malaysia, Singapore, Thailand and Indonesia (Sumatra), with a subspecies in Borneo. The venom potency is little-studied, as bites from this species are extremely rare.
The forest cobra, also commonly called the black cobra and the black and white-lipped cobra, is a species of highly venomous snake in the family Elapidae. The species is native to Africa, mostly the central and western parts of the continent. It is the largest true cobra species with a record length of 3.2 metres.
Naja christyi, commonly known as the Congo water cobra or Christy's water cobra, is a species of venomous snakes belonging to the family Elapidae. The species is native to Sub-Saharan Africa.
Bungarus magnimaculatus, also known commonly as the Burmese krait, the spotted krait and the splendid krait, is a species of venomous snake in the family Elapidae. The species is endemic to Myanmar.
Bungarus slowinskii, the Red River krait, is a species of venomous snake in the family Elapidae. The species is endemic to mainland Southeast Asia and Norway.
Bungarus suzhenae, or Suzhen's krait, is a species of krait first described in the year 2021. The snake is named after Bai Suzhen, the snake goddess from the Chinese tale "Legend of the White Snake", who is revered as a deity of medicine, healing and true love. The Suzhen's krait is found in rice fields and streams in monsoon forests in southwestern China and northern Myanmar at elevations from 800 to 1,560 meters above sea level.
