Long-rayed Sand Diver

Found in harems, hovering above sandy slopes, diving head first into the sand if disturbed, or buried in the sand when there is no current running, over channels, coastal reefs, and deep outer reefs.

Sand Divers get their name because when alarmed or predators are near, they dive into the sand and swim through the sand to safety.
Males displaying filaments in the dorsal fin, which they use to keep the females and juveniles following close behind.
