But Andy Casagrande found a gap in the POV footage market. While diving, he saw the opportunity to for a GoPro to the dorsal fir on a Hammer Head shark.
Initially, the shark looks a little distressed at having something usual attached too it, but soon appears to settle down.
The incredible footage, shot in 4K if you've got a NASA computer and a few surplus litres of internet, is absolutely stunning, giving us a Blue Planet style look at what Hammer Heads spend their day doing.
It turns out, they hang out with other sharks, have little fish cling on to their heads, and do some rad-looking side swimming - the equivalent of the kids from the shopping precinct doing wheelies outside Greggs The Bakers.
