These are white-tip reef sharks (not Oceanic white-tip sharks), and they exhibit a behavior of resting for long periods of time under coral heads or in crevices, often piling up one on top of the other.
When it comes to resting, white-tip reef sharks use a ventilation system called buccal pumping. This system allows them to stay still and pump water through their gills by simply opening and closing their mouths.
This is a perfect example of the vast diversity among sharks, of why “one size does not fit all” applies when discussing sharks and the different characteristics of each species.

These sharks were resting on a shelf at Roca Partida.
