Etymology: Physalias is the plural of "physalia", the name for a genus of floating marine hydrozoans, the colonies often called Portuguese man o' war. The singular "physalia" is the form the word takes in technical use, borrowed as a Latinised scientific name for the genus, and the plural follows the regular Latin-style pattern of adding "s" when more than one colony is meant.

Synonyms: Portuguese man o' war
