In fact this is one of the first recordings of Great White
sharks by scuba divers this far north in the western Indian
Ocean. This particular animal was apparently 4 metres (13 feet)
in length and as can be seen from the photographs was certainly
curious of the divers.

Quite what a Great White is doing in such warm waters is hard to
say, however the sharks are regarded as subtropical, occurring
between 60°N - 50°S latitude and listed as being found, even
if rarely, in both Mauritius and Seychelles by Fricke in his
book 'Fishes of the Mascarene islands' (Koeltz Scientific
Publications).
Like the whale shark, Great Whites are ovoviviparous, the
embryos are retained inside the mother feeding on yolk sac and
other ova produced by the mother. Unlike the whale shark they
have been implicated in attacks on humans who they apparently
mistake for their normal prey such as seals.
The notoriety of Great Whites fostered by Hollywood and the film
“Jaws” has lead to a lucrative market for white shark
products that encourages illegal hunting and trading that is
difficult to assess and control. The species is listed on CITES
Appendix III, since May 2003 but this has little effect in
controlling local fisheries and the limited population data
available indicates that the abundance and average size of white
sharks is in decline. The species is now protected in some parts
of its range but the effectiveness of such protection is
questionable where enforcement is weak.
