Do sharks like belly rubs?
As one Redditor noted, “no matter who or what you are, you can’t pass up a good belly rub.” This affectionate little interaction goes on for well over a minute before the shark drifts off and the diver picks up right where he left off, like giving belly rubs to sharks is all in a day’s work!
