Etymology: "Ciguatoxin" is a compound built from two parts: "ciguatera," the name of the human illness caused by eating tainted fish, and "toxin," a poison produced by a living organism. The first half comes from the Spanish "cigua," a word used in the Caribbean for a sea snail, a name that was applied to the illness because it was linked to eating reef fish that had fed on contaminated marine life. The name of the toxin therefore reflects its role as the chemical cause of that illness. Scientists isolated the substance and gave it a label that points straight back to the disease, so anyone who knows the suffix "-toxin" can read the word as "the poison responsible for ciguatera." Its structure mirrors the way toxins are commonly named after the condition they produce.
