Sense: noun/1
An eel is a fish that lives in water and looks like a snake, but the two animals are very different. A snake is a land reptile with dry scaly skin and lungs; it breathes air and many species live in deserts or forests. A sea snake is also a reptile — venomous and air-breathing — though it hunts in the ocean. A lamprey looks similar to an eel but has a round sucking mouth without jaws and is not commonly eaten. A worm is a small soft-bodied invertebrate that lives in soil, not water, and has no bones at all. Think of an eel as a real fish that just happens to have a long snakelike shape: it has gills, fins, and lives its whole life underwater.

Etymology
The word 'eel' comes from Old English 'ǣl', which developed from Proto-Germanic *ēlaz. Related words appear across the Germanic languages, such as German 'Aal' and Dutch 'aal'. The origin before Proto-Germanic is unknown. The verb meaning 'to move like an eel' appeared by the 1600s, while the fishing senses are later regional developments.
