Big Fish
Mola Mola (Ocean Sunfish)
Mola mola · Bony fish, family Molidae
The sunfish looks like the ocean ran out of fish halfway through building one: a huge silver head that simply stops, finished off with a scalloped rudder where the tail should be. Then it moves, and the joke dies: a big mola sculls past with unhurried authority, an eye the size of a plum tracking you, on its way to hang tilted at a cleaning station while bannerfish groom it like pit crew. Bali's cold-upwelling season delivers the world's most reliable encounters, strange gray giants materializing out of thermocline haze at Crystal Bay. It remains one of diving's oddest and most coveted sightings: a deep-sea jellyfish-eater moonlighting as a wall ornament.

Capirle
Habitat: Open ocean through the water column; rises to cleaning stations on reef walls and basks flat at the surface after cold deep dives
Distribuzione: Temperate and tropical oceans worldwide; diver encounters cluster at Bali's channel reefs, the Mediterranean, California, and the Azores
Comportamento: A vertical dinner-plate of a fish that flaps along on dorsal and anal fins, yaws like a badly trimmed kite, and queues at cleaning stations where bannerfish pick its parasites. Surface basking (lying flat, side up) warms it after deep foraging. Utterly placid around divers unless crowded off the station.
Dieta: Jellyfish and other gelatinous plankton, plus small fish and zooplankton, a low-calorie diet consumed in bulk
Dimensioni: tipicamente intorno a 1.8 m; documentato fino a 3.3 m (total length; among the heaviest bony fishes, with big animals beyond a tonne. Bali's famous 'mola' is now identified as the bump-head sunfish, Mola alexandrini).
Come comportarsi in sua presenza
Nusa Penida's code of conduct is the model: stay behind the reef line at cleaning stations, minimum distances, no flash barrages, no bubbles beneath a cleaning fish, and never chase a departing mola; it won't come back that day.
Conservazione
Vulnerable: vast numbers die as bycatch in drift and set nets worldwide; its slow-motion surface basking makes it easy accidental catch.
