Meet the Mola Mola while Scuba Diving in Bali

  |   Diving In Bali

Have you heard of the “mola mola” or “sunfish”? Did you know that Bali is one of the few places on the planet here you can dive with this amazing marine species?

What is a Mola Mola?

The mola mola is one of the strangest looking fish in the ocean and it’s also the heaviest known bony fish in the world. This incredible marine species can weigh in at over 2,200lbs and it has two dorsal fins which make it as tall as it is long. The most distinguishing feature of the mola is its main body area – of which there is very little – and which is flattened laterally. This strange shaping explains the German name for the fish – ‘schwimmender kopf’ which translates literally to ‘swimming head’. The word ‘mola’ is actually latin and means ‘millstone’ perhaps referring to either it’s disc shaped body or marbled coloration.
Mola live on a diet of nutritionally poor jelly fish and to maintain their body weight they consume huge quantities. Ordinarily they are deep water fish but here in Bali they are seen around Nusa Penida (a marine protected area) from late June through to November – so the time to dive with them is now!

A symbiotic relationship

One of our favourite sites for seeing mola is Crystal Bay where we watch them cruise up the reef hoping to attract the attention of the smaller reef fish which “clean” them. Mola mola attract many parasites and these are eaten by their smaller companions – leaving them clean and the smaller fish well fed – a perfect symbiotic relationship.
Most commonly we see schooling bannerfish cleaning the mola but butterflyfish and angelfish often join in too.
They are a truly pre-historic looking fish which, as a member of the order Tetraodontiformes, are closely related to pufferfish, porcupine fish and triggerfish. The mola is also referred to as the Balinese Sunfish (or Moonfish to the French – Poisson Lune). The name sunfish is thought to come from its habit of ‘sunbathing’ on the surface of the water.
