Unlike most sharks, the nurse shark does not have to constantly move water across its gills to breathe.
Unlike most sharks, the nurse shark does not have to constantly move water across its gills to breathe. The nurse shark can remain motionless on the seafloor because of its ability to pump water across its gills. It does this by opening and closing its mouth. This design was given to the nurse shark by its Creator.
