This is a high-definition underwater realistic photo, showing a swell shark resting on the sandy seabed made of broken shell gravel. This small benthic shark with characteristic dark brown spots stays quietly near the algae-covered reef. Swell sharks can inflate their bodies by swallowing seawater to deter predators when in danger, the picture presents the quiet original ecology of the seabed.
