Oh ya.......that looks like REAL fun.........until you see those jagged edge teeth drop down to attack mode.
My brother was diving off Corpus Christi, Texas a couple of weeks ago. He was freediving with some friends of his and they had spear guns. They didn't see much around the oil rigs so they followed a shrimp boat that was cleaning its catch. They swam over to see if any critters were feeding off the scraps being thrown overboard. Within minutes a big pod of dolphins showed up, jumping and spinning out of the water. They passed so close you could touch them. And then shortly behind them came a group of five silky sharks. The sharks and dolphins mingled together making runs at the shrimp scrap as the fishermen shoveled it off the boats. My brother said he was surprised that they didn't seem to mind each other.
Then a tiger shark showed up. This made all the divers a tad nervous as it does have an aggressive reputation as being fearless around humans. However, one of the divers had an electronic shark repeller. It puts a 15 foot radius orb of electrical current that sharks hate. My brother said the tiger shark swam over to them to check them out, hit the 15 foot "wall" and abruptly turned and left them alone.
