Tawny nurse shark in the Maldives

Maldives field guide · shark

Tawny nurse shark.

Nebrius ferrugineus · also: Giant sleepy shark

A heavy-bodied, sluggish bottom-dweller with tiny eyes and trailing barbels, often found dozing in caves by day, sometimes piled in groups. It is a powerful suction-feeder, able to vacuum prey out of crevices with an audible slurp. Slow and docile, but its small mouth generates remarkable suction force.

Its suction feeding is strong enough to be heard underwater — it can spit and re-suck prey to reposition it.
