Sorry I can't see the video to comment but Hammerheads are particularly dangerous. Somewhat related, and maybe off topic a bit...haven't seen the video and can only imagine the shark was in shallow water, because tarpon fishing is usually in the shallows.
Back in the 30's my Dad and his shipmates hung a white rag on a large hook attached to a rope and dropped it off the back of their cargo ship anchored somewhere in South America (maybe near Buenos Aires in the Rio Plata.) It wasn't long before they caught an 8' Mako shark and when they cut it open there was about a 50 lb. chunk of ambergris inside. Ambergris was used back in those days to make perfume. Raw ambergris fetches approximately US$10 per gram (as of 2006), with much higher prices possible for particularly high-quality samples...making this discovery worth about $8000+ in today's money. No telling what it was worth during the Depression. The captain took the ambergris and threw it overboard, as they had no way to get it to market, or the captain thought it might cause problems if they did keep it, getting it to market, how to divide up the loot, possible theft or mutiny, etc...
Interesting thing about it is, usually ambergris is found in whales and this was found in a Mako shark... rare I have heard but possible. Makos are considered game fish and it may be any large or aggressive shark would be in that category. Interesting subject sharks.
