The Family Elapidae is a group of venomous snakes that includes cobras, kraits, mambas, coral snakes, and sea snakes. They are characterized by fixed, hollow front fangs used to deliver potent neurotoxic venom, which can immobilize prey quickly. Elapids are generally slender, fast-moving, and highly adaptable, inhabiting a wide range of environments from forests and deserts to oceans. Most are predatory, feeding on small mammals, birds, reptiles, amphibians, or fish. Ecologically, they play important roles as mid- to top-level predators, helping control populations of their prey, while some species, like cobras and sea snakes, have significant interactions with humans due to their venomous nature.
