the.com/electric eel

means A South American fish (not a true eel) that generates powerful electric shocks using specialized organs running most of its body length, used for hunting, defense, and sensing its surroundings.

from English simply bolts together "electric" and "eel" — descriptive, not poetic, naming the eel-like body shape plus its signature shock. "Eel" is an old word (related to Old English "ǣl") for long, slippery fish, though this creature is actually more closely related to catfish and carp than to true eels. "Electric" traces back to the Greek "ēlektron," meaning amber — because ancient Greeks noticed rubbed amber could attract light objects, a mysterious force later named after it. The fish's scientific name, Electrophorus, literally means "electricity bearer," and early naturalists studying its shocks in the 1700s helped spark (so to speak) the whole modern science of electricity.
