Timing is everything (my SOP); just a couple hours before Doug posted his video link I snapped this pic in the Bubble Cave! There were only 2 in the Sand Cave but when we looked under the shelf in the next cave we saw this
bunch of fins cozied up together;
With close scrutiny you can make out 6 adults, which is the most I have seen at one time anywhere in Hawaii. As for hooked sharks in the Makena area, I doubt there are many adults who haven't been hooked at one time in their life (see my current Makena dive thread). When I see hooks now I am glad,
glad as all get out; at least these fishers are letting them go and the sharks seem to survive the ordeal.
IMHO to get relevant data on agonistic behavior (never heard of or observed it amongst Hawaii's white tip reef sharks) you would need to at least use a rebreather, but probably really use remote video with really long recording times or hard wired to a monitor with DVR'ish qualities so a few minutes after interesting activity starts you can start the recording before said activity started.
It would seem to me that anytime a diver is close enough to
study our reef sharks the reef sharks change their
natural behavior to include studying the diver (
naturally), which then is not the
natural behavior the diver hoped to study! The house sitting pretty much right above the Sand and Bubble caves is for sale, probably significantly reduced from the original $20 Mil listing!
