Best places to dive with Giant sunfish (bump-head mola)
Mola alexandrini
Mola alexandrini has never been assessed by the IUCN Red List — FishBase records it as Not Evaluated and it does not appear in the Red List checklist — so conservation status is recorded as unknown rather than guessed. Not Evaluated is not a clean bill of health: the closely related Mola mola is assessed as Vulnerable, and the IUCN Molidae review panel flagged the giant sunfish as a priority for a first assessment.

Present in the area year-round from the surface to well below recreational depth, but divers encounter them mainly between about July/August and November — the locally named sunfish season — when southeast-monsoon upwelling brings cold Indian Ocean water up the southern and western coasts. Crystal Bay is the best-known site, with Blue Corner, Toyapakeh and the north-coast drifts also producing them. Encounters are usually deep and brief, and nothing about them is scheduled.
