Nusa Penida is an internationally renowned diving destination, famous for its majestic manta rays and, of course, the elusive mola mola. These friendly giants of the deep, also known as ocean sunfish, attract divers from around the world, eager to witness their unique beauty.

But why are mola mola sightings seasonal? These deep-sea inhabitants inhabit the cold depths of the ocean. However, during Bali’s dry season (July to November), cooler currents upwell around Nusa Penida, creating conditions for the molas to ascend to shallower waters.

A Curious Physiology:

The mola mola is a truly extraordinary fish. Its unique, almost circular and flattened body shape has earned it the nickname “ocean sunfish.” They lack a traditional caudal fin, instead possessing a “clavus,” a rounded structure they use for propulsion. Their thick, leathery skin can harbor numerous parasites, which explains their pursuit of cleaning stations.

They can reach impressive sizes, exceeding 3 meters in length and 2 tons in weight, making them the heaviest bony fish in the world. Despite their size, they feed primarily on zooplankton, jellyfish, and small fish. They are usually found in open water, but they perform vertical migrations to forage or regulate their body temperature.

Such ascents serve a vital purpose. Mola mola visit “cleaning stations” where reef fish help remove parasites from their skin. This behavior offers divers a rare opportunity to observe these creatures up close.

While mola mola can be seen year-round in deeper waters, the chances of encountering them while diving increase significantly during the dry season. At Temple Diving, we specialize in guiding divers to the best mola mola spots, ensuring a safe and unforgettable experience.
