Diver finds nurse sharks snuggling in group snooze under reef

ADDU CITY, Maldives, April 25 (UPI) -- A diver examining a reef off the coast of Gan in the Maldives came across a group of nurse sharks enjoying a sub-aquatic snuggle at naptime.

The diver shared video of the 10-foot nurse sharks sleeping under a reef in a way that the uploader said might seem unusual for sharks.

"These sharks are unlike many other types of sharks that need to swim forward in order to breath," the uploader wrote.

"These sharks are capable of opening and closing the mouth (like moray eels) and this forces oxygenated water over the gills (breathing)," the post said. "They are nocturnal and will be mainly active at night when they are on the hunt for food."
