Lionfish

The common lionfish found across the Indian Ocean is a slow-moving ambush predator with venomous dorsal spines and a habit of hovering motionless at wreck entrances. It feeds on small fish and crustaceans and is typically more active at dawn and dusk. On wrecks like the Stella Maru it occupies crevices and overhangs, making it easy to photograph but important not to touch.
