Etymology: Lophobranch is a compound built from two Ancient Greek nouns: "lóphos", meaning "crest" or "tuft", and "bránkhia", meaning "gills". Put together, the name describes the fish's most distinctive feature. Lophobranchs, the group that includes seahorses, pipefishes and their relatives, have gills that are arranged in small tufts or clusters rather than the broad, comb-like gill plates of most other fish. The compound is a straightforward descriptive coinage, so its interest lies in how neatly the Greek parts map onto the animal's anatomy. Its first element, "lóphos", is the same root that gives English "lophodont" and other scientific terms for crested or ridged structures, a reminder that classical vocabulary was repeatedly mined by naturalists to name newly described animals.
