Big Sime is a 4.3m, very powerfully built male, who arrived in September 2007, in the winter season, at North Neptune Island.
Contrasting with his relatively dark body, he displays a large flash of white markings on his lower tail fin, as well as on his gill plates.
Big Sime is prominent around our submersible observation cages down on the ocean floor, dominating the bottom cage diving action. He is a very confident shark and approaches cages, the boat platform and other large sharks with confidence at most times. He is therefore a favourite among many divers who have had the pleasure of observing him up close!
