Definitions

Etymology: In ancient Greek, "hydōr" meant "water" and "philos" meant "loving" or "fond of." "Hydrophilus" joins these two parts into a Latinized name for a genus of beetles, the water scavenger beetles, many of which spend most of their lives submerged in ponds and slow streams. The name is a modern scientific coinage built from classical elements. No ancient Greek writer used it for an animal. The same pairing appears in "hydrophilic," a chemistry term for substances that dissolve in or are attracted to water. Like the beetle name, it reuses the Greek roots in a new technical sense, so "water-loving" describes both a creature and a molecule.
