NajaNaja is a genus of venomouselapidsnakes commonly known as cobras (or "true cobras"). Various species occur throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are often called "cobras", such as the king cobra and the rinkhals, but they are not "true cobras", in that they do not belong to the genus Naja.
King cobraThe king cobra (Ophiophagus hannah) is a species complex of snakes endemic to Asia. With an average length of 3.18 to 4 m (10.4 to 13.1 ft) and a record length of 5.85 m (19.2 ft), it is the world's longest venomous snake and among the heaviest. Under the genus Ophiophagus, it is not phylogenetically a true cobra despite its common name and some resemblance.
CobraCobra is the common name of various venomous snakes, most of which belong to the genus Naja. Many cobras are capable of rearing upwards and producing a when threatened.
RinkhalsThe rinkhals (; Hemachatus haemachatus), also known as the ringhals or ring-necked spitting cobra, is a species of venomous snake in the family Elapidae. The species is found in parts of southern Africa. It is not a true cobra in that it does not belong to the genusNaja, but instead belongs to the monotypic genus Hemachatus.
SnakeLimbless, scaly, elongate reptileSnakes are limblessreptiles of the squamate suborder Serpentes.
SpeciesBasic unit of taxonomic classification, below genusThe hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown.A species (pl. species) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.
AfricaAfrica is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km (11.7 million square miles) including adjacent islands, it covers around 20% of Earth's land area and 6% of its total surface area. With nearly 1.4 billion of the world population, Africa's population is the youngest among the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4.
ElapidaeElapidae (, commonly known as elapids , from Ancient Greek: ἔλαψ élaps, variant of ἔλλοψ éllops "sea-fish") 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.GenusGenus (; pl.: genera) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. E.g. Panthera leo (lion) and Panthera onca (jaguar) are two species within the genus Panthera.
Taxonomy (biology)In biology, taxonomy (from Ancient Greek (taxis)'arrangement' and ()'method') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics. Modern approaches prioritize common ancestry and evolutionary relationships.
Southeast AsiaSubregion of the Asian continentSoutheast Asia is the geographical southeastern region of Asia, consisting of the regions that are situated south of China, east of the Indian subcontinent, and northwest of mainland Australia, which is a part of Oceania. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia and the Indian Ocean.
VenomVenom or zootoxin is a type of toxin produced by an animal that is actively delivered to other animals through a wound by means of a bite, sting or similar penetrative action, usually via a specially evolved venom apparatus, such as fangs or a stinger, in a process called envenomation.
South AsiaSouth Asia is the southern sub-region of Asia that is defined in both geographical and ethnic-cultural terms. South Asia, with a population of 2.04 billion, contains a quarter (25%) of the world's population. As commonly conceptualised, the modern states of South Asia include Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka, with Afghanistan also often included, which may also be classified as part of Central Asia.Special:Search/najaRelated word or term.*As an Amazon Associate I earn from qualifying purchases.
