Hairy frogfish are among the ocean's most accomplished ambush predators, deploying a lure — the illicium — above their mouth to attract prey within striking distance, then engulfing victims in a strike lasting under six milliseconds, one of the fastest predatory strikes of any vertebrate. Their extraordinary skin appendages, which resemble alga or hydroids, provide camouflage so precise that the fish is essentially invisible against matching substrate. Multiple colour morphs exist within a single species; an individual can change colour over weeks to match a new microhabitat. Ambon Bay is the most reliable site on earth for multiple hairy frogfish encounters on a single dive.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
