Venomous snake in the context of "Viperinae"

Asp is the modern anglicisation of the word "aspis", which in antiquity referred to any one of several venomous snake species found in the Nile region. The specific epithet, aspis, is a Greek word that means "viper". It is believed that aspis referred to what is now known as the Egyptian cobra.

The Egyptian cobra (Naja haje) is one of the most venomous species of snakes in North Africa. It averages roughly 1.4 metres (4.6 ft) in length; the longest specimen recorded so far measured 2.59 metres (8.5 ft).

The 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. Spanning from the Indian subcontinent through Southeastern Asia to Southern China, the king cobra is widely distributed albeit not commonly seen.

Individuals have diversified colouration across its habitats, from black with white strips to unbroken brownish grey, although after taxonomic re-evaluation, it is no longer the sole member of its genus but is now a species complex; these differences in pattern and other aspects may cause the genus to be split into at least four species, spread across its large geographic range.

Vipera aspis is a viper species found in southwestern Europe. Its common names include asp, asp viper, European asp, and aspic viper, among others. Like all other vipers, it is venomous. Bites from this species can be more severe than from the European adder, V. berus; not only can they be very painful, but approximately 4% of all untreated bites are fatal. The specific epithet, aspis, is a Greek word that means "viper." Five subspecies are currently recognized, including the nominate subspecies described here.

Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant– alters the normal activity of the nervous system in such a way as to cause permanent or reversible damage to nervous tissue. This can eventually disrupt or even kill neurons, which are cells that transmit and process signals in the brain and other parts of the nervous system. Neurotoxicity can result from organ transplants, radiation treatment, certain drug therapies, recreational drug use, exposure to heavy metals, bites from certain species of venomous snakes, pesticides, certain industrial cleaning solvents, fuels and certain naturally occurring substances. Symptoms may appear immediately after exposure or be delayed. They may include limb weakness or numbness, loss of memory, vision, and/or intellect, uncontrollable obsessive and/or compulsive behaviors, delusions, headache, cognitive and behavioral problems and sexual dysfunction. Chronic mold exposure in homes can lead to neurotoxicity which may not appear for months to years of exposure. All symptoms listed above are consistent with mold mycotoxin accumulation.

The term neurotoxicity implies the involvement of a neurotoxin; however, the term neurotoxic may be used more loosely to describe states that are known to cause physical brain damage, but where no specific neurotoxin has been identified.

Sea snakes, or coral reef snakes, are elapid snakes that inhabit marine environments for most or all of their lives. They belong to two subfamilies, Hydrophiinae and Laticaudinae. Hydrophiinae also includes Australasian terrestrial snakes, whereas Laticaudinae only includes the sea kraits (Laticauda), of which three species are found exclusively in freshwater. If these three freshwater species are excluded, there are 69 species of sea snake divided among seven genera.

Most sea snakes are venomous, except the genus Emydocephalus, which feeds almost exclusively on fish eggs. Sea snakes are extensively adapted to a fully aquatic life and are unable to move on land, except for the sea kraits, which have limited land movement. They are found in warm coastal waters from the Indian Ocean to the Pacific and are closely related to venomous terrestrial snakes in Australia.

In ancient Egypt, cats were represented in social and religious scenes dating as early as 1980 BC. Several ancient Egyptian deities were depicted and sculptured with cat-like heads such as Mafdet, Bastet and Sekhmet, representing justice, fertility, and power, respectively. The deity Mut was also depicted as a cat and in the company of a cat.

Cats were praised for killing venomous snakes, rodents and birds that damaged crops, and protecting the Pharaoh since at least the First Dynasty of Egypt. Skeletal remains of cats were found among funerary goods dating to the 12th Dynasty. The protective function of cats is indicated in the Book of the Dead, where a cat represents Ra and the benefits of the sun for life on Earth. Cat-shaped decorations used during the New Kingdom of Egypt indicate that the domesticated cat became more popular in daily life. Cats were depicted in association with the name of Bastet.

The Indian cobra (Naja naja /nadʒa nadʒa/), also known commonly as the spectacled cobra, Asian cobra, or binocellate cobra, is a species of cobra, a venomous snake in the family Elapidae. The species is native to the Indian subcontinent, and is a member of the "big four" species that are responsible for the most snakebite cases in Sri Lanka and India.

The Indian cobra is revered in Hindu mythology and culture, and is often seen with snake charmers. It is a protected species under the Indian Wildlife Protection Act (1972).
