Barracuda

Barracudas are predatory schooling fish with long bodies, prominent teeth, and a habit of forming dense circular schools, or 'tornadoes', at seamounts and reef points. The chevron barracuda (Sphyraena qenie) is the species that makes Sipadan's Barracuda Point famous, with schools of 500+ swirling at 5–15 metres above the coral.

Solitary great barracudas (Sphyraena barracuda) are larger, more aggressive predators that hang in mid-water near reef edges. Most divers see them at every Indo-Pacific destination, hovering motionless and eye-tracking smaller fish for an ambush strike.

Sipadan and the Red Sea (Ras Mohammed) for tornadoes. Single barracudas at Maldives, Andaman, Bali, Phuket and Komodo, at every reef. Approach calm and slow; they don't react to divers but will spook from sudden movement.
