It also depends on which direction you rub the skin. Blue sharks for example: if you rub from head to tail they seem smooth but go from tail to head their skin is like sandpaper. Sandys are rough in either direction and many times when people are in waist deep water and they feel something rough brush past then "assume" it was rough sea grass were actually grazed by a sand shark passing by.
As a kid my friends and I used to catch sand sharks by hand and then grip them by the dorsal fin and "walk" them like a dog. They have about shit for teeth and a staple in their diet is small clams, scallops and mollusks. Their jaws are more bony plate than teeth which they use to crush the shells and eat the tasty rewards found within. Small fish are also part of their diet as John said.
From the looks of it on the video, they had a fish ball going. Note the color of the water where the sharks are feeding. It indeed looks like brown (dusky) sharks from what I can see.
