What does elapid mean?
An elapid is any member of Elapidae, the large family of highly venomous snakes that includes cobras, mambas, kraits, taipans, coral snakes, and sea snakes. What unites them anatomically are their short, permanently erect fangs at the front of the mouth — unlike the hinged, folding fangs of vipers — and, in most species, venom that acts primarily on the nervous system, producing paralysis rather than the tissue destruction typical of viper bites. Elapids occur across tropical and subtropical regions worldwide, with Australia especially rich in them. The word belongs mainly to scientific and technical registers: a wildlife documentary might describe a 'deadly elapid,' while everyday conversation would simply say 'cobra' or 'mamba.' Knowing the term is useful precisely because it groups together many superficially different snakes under one medically significant label.
nounA venomous snake belonging to the family Elapidae, which includes cobras, mambas, kraits, coral snakes, and taipans, characterized by fixed hollow fangs at the front of the mouth through which neurotoxic venom is injected.
- Any venomous snake of the family Elapidae, such as a cobra, mamba, krait, taipan, or coral snake.
"The herpetologist identified the serpent as an elapid by its small, immovable front fangs and the distinctive hood it flared in warning."
"The inland taipan, often called the most venomous land snake in the world, is an elapid native to Australia."
"Because elapid venom is primarily neurotoxic, bites can cause paralysis within hours if antivenom is not administered."
Standard regular plural; commonly used when discussing the family as a group.
"Many elapids deliver dry bites in which no venom is injected."
From the king cobra to the coral snake, every elapid carries its killing hardware permanently exposed — unlike vipers, they can never fold their fangs away.

Etymology of elapid
The word derives from New Latin Elapidae, the family name coined in the nineteenth century by German naturalist Heinrich Boie, built on the Greek éllops, a term used by ancient writers for a kind of snake. The Greek root passed into scientific Latin as the basis for the family classification, from which English formed the common-noun form 'elapid.' Its history is therefore essentially scientific-taxonomic rather than part of the older vernacular vocabulary.
How elapid is actually used
A technical term used chiefly in herpetology, zoology, and scientific writing rather than everyday speech; general readers would usually name the specific snake (cobra, mamba) instead.
Easily confused with elapid
Vipers are a different venomous family (Viperidae) with long, hinged, folding fangs, whereas elapids have short, fixed front fangs and tend toward neurotoxic venom.
