The vacuum-cleaner shark. Sucks crustaceans from holes, sleeps stacked under ledges, ignores divers entirely.
Nurse sharks are the laziest sharks on the reef — they spend daylight piled in caves or resting flat on sand, only stirring at night to feed. The Indo-Pacific tawny nurse (Nebrius ferrugineus) reaches 3 metres; barbels on the snout act like sensory antennae for finding prey buried in sand.
They suction-feed through a small mouth, vacuuming up crustaceans, octopus, small fish. The action is comical to watch — head jammed into a hole, gill flares pumping water out the back. Maldives night dives are the gold standard for active nurse encounters.
Reliable sightings: Maldives (especially Alimatha night dive — the famous nurse shark aggregation), Andaman walls, Phuket / Similan deeper sites, Red Sea. Daytime encounters are sleepy. For the action, dive after sunset.
