Etymology: The Greek word "akalephē" meant "stinging nettle," and it is the plant's sting that gave the name to these jellyfish-like animals. Greek writers used the word for the nettle long before anyone applied it to the sea. When English-speaking naturalists borrowed the term from Latin "acalephe," they kept the nettle's sting in the name, reaching for a plant everyone knew from brushing against it in a field to describe the painful contact of a jellyfish's tentacles on skin. "Acalephs" is the plural form, and it refers to the group of marine creatures collectively known as jellyfish, the animals sometimes called sea nettles in ordinary speech.

Synonyms: jellyfish, cnidarians
