Acanthurus nigrofuscus – Brown Surgeonfish

No species profile available for Acanthurus nigrofuscus – Brown Surgeonfish.


Surgeonfish have razor sharp “knives” at the base of their tail. These retractable extensions are a natural defence against predators. They only extend if the fish feels agitated or when threatened. They can inflict  real deep lacerations that often start to infect. The infected skin starts to swell and make the skin change colour. This can last for several hours. Because the cuts cause infections so often it is believed Surgeonfish have poison glands.
