A genus of frogfish, or a specific type of antennariid fish characterized by distinctive antenna-like appendages.
From Latin 'antenna' (feelers or horn-like structures), with the masculine Latin nominative singular ending '-us' used in scientific nomenclature.
When Linnaeus and early naturalists named sea creatures, they often described what they saw based on land animals they knew—so frogfish got their 'antenna' names because their fishing lures vaguely resembled insect antennae when seen in preserving jars.
