Here's an additional note from Larry...
...we were coming in from fishing and I saw a big fin out of the water just off the 2nd bar... figured it was a big hammerhead as they commonly cruise right on top. We went over to look and it was a HUGE Mako (1,000 punds) just easing along right on top. he'd let us get within 50 feet and then slowly ease down just to pop right back up once he was 100' or so away. just kinda milled around in 25' of water, not in any hurry or scared of us. we estimated 14 feet long. All my pics are just pretty green water with a dark spot... way to much afternoon glare to see anything at all.
FYI from Wikipedia
[h=3]Attacks on humans[/h]
ISAF statistics records 42 shortfin
attacks on humans between 1980 and 2010, three of which were fatal, along with 20 boat attacks.[SUP]
[27][/SUP] This mako is regularly blamed for attacks on humans and, due to its speed, power, and size, it is certainly capable of injuring and killing people. However, this species will not generally attack humans and does not seem to treat them as prey. Most modern attacks involving Shortfin mako sharks are considered to have been provoked due to harassment or the shark being caught on a fishing line.[SUP]
[28][/SUP] Sharks can be attracted to spear fishermen carrying a stuck fish, and may slap them with
cavitation bubbles from a swift tail flick. Divers who have encountered shortfin makos note, prior to an attack, they swim in a figure-eight pattern and approach with mouths open.[SUP]
