Most deadly (didn't look like they could be arsed to kill you TBH)
Komodo Dragon, quite afew of them on Rinca island ,komodo park ,indo 2004,
most frightnening,
a pair of lion fish the size of medicine balls, nearly bumped into one while spearfishing on the reef off seraya cercil island, flores ,indo, that would have been the last thing i did as the hospital was an hour away and the boat could not have left the island because it was low tide,
best,
huge sea turtle just popped up next to us few miles off shore of seraya
when we were out on the dugout boat, massive and scared the crap out of me,
