Bluestriped fangblenny in the Indian Ocean
Perhaps the bluestriped fangblenny smiles because it keeps fooling larger fish. This reef-dweller swims in both the Indian and Pacific Oceans. It mimics the bluestreak cleaner wrasse, a fish that ‘cleans’ larger fish by picking off dead scales, parasites, and other detritus. The fangblenny, however, is an aggressive mimic. It hangs out at cleaner stations and dupes larger fish into thinking it will give them a spa treatment just like cleaner wrasses do, but instead of cleaning, it takes bites of flesh. And its bite delivers a morphine-like venom that slows down the aggrieved big fish, giving the fangblenny time to swim to safety if its cover is blown.
