Without wishing to add fuel to the flames, I should add that spinners are
present in the Indo-Pacific as well. I have seen one underwater at Western
Rocky in Burma, and a colleague of mine just returned from diving the island
of Bohol in the Philippines. She claims to have seen several on every dive
over a week-long trip. I suspect many confuse them with black-tips, or,
because of the pointed snout,
with makos (which, incidentally, are also known to breach).
