means A slender, brilliantly banded venomous snake whose red, yellow, and black rings warn predators off while its small, fixed fangs deliver a potent neurotoxic bite.

from The 'coral' in the name comes straight from the snake's red-hued banding, likened to the reddish-pink color of coral (the marine organism), whose own name traces back through Latin 'corallium' to Greek 'korallion' — ultimately of uncertain, possibly Semitic, origin. The name has nothing to do with the sea beyond that borrowed blush of color. Famously, the snake's lookalike mimics (milk snakes and kingsnakes) gave rise to the folk rhyme 'red touch yellow, kill a fellow; red touch black, friend of Jack' — a genuinely useful mnemonic in the Americas, though not a reliable rule for coral snakes worldwide.
