In the waters of the Indian Ocean, few creatures spark curiosity like the ocean sunfish, also known as Mola mola. This giant fish stands out not only for its size but also for its unique, almost alien-like appearance, captivating both scientists and ocean enthusiasts across South Africa.
With its flat, round body and gentle demeanor, the ocean sunfish is often described as one of the ocean’s most intriguing species.
Found in various aquariums and coastal regions, its fascinating characteristics continue to draw attention, making it a symbol of the ocean’s mysterious allure.

Dive in and discover everything you never knew about this enigmatic creature that roams the waters off the coast of South Africa.
What is the Ocean Sunfish ?
The ocean sunfish, or Mola mola, is one of the largest bony fish in the world. It can reach an astonishing weight of up to 2,000 kilograms and a diameter of over 3 meters.
Despite its size, this remarkable fish is known for its passive nature and distinctive appearance. Its body, which resembles a massive disc, lacks a typical fish tail and instead features a unique structure called the “clavus.” This modification gives the fish its distinctive, almost moon-like shape — hence the name ocean sunfish.
Unlike many other fish species, the ocean sunfish has a relatively small mouth and feeds primarily on jellyfish. This diet may seem unusual for such a large creature, but it allows the fish to thrive in the open ocean.
With its surprising adaptability, the ocean sunfish has evolved to live in diverse environments, from the warm coastal waters of South Africa to deeper ocean currents. Its diet and behavior make it an integral part of the ocean’s ecosystem.
While the ocean sunfish may appear intimidating due to its size, it is a gentle giant that poses no threat to humans. Instead, its behavior is often described as calm, making it a favorite among divers and marine photographers. The ocean sunfish’s passive nature and intriguing features make it one of the most fascinating creatures to observe in the wild.
Where Does the Ocean Sunfish Live?
The ocean sunfish is found in temperate and tropical waters around the globe.
In South Africa, it is a common sight along the coasts of the Indian Ocean, particularly in regions like Durban and Cape Town.
This fish is known to migrate between different depths of the ocean, often found at the surface basking in the sun — which is where it gets its common name, “sunfish.”
These marine giants are typically solitary creatures but can occasionally be seen in groups during migration.
Ocean sunfish are known to migrate long distances, sometimes traveling between different oceanic regions to find food or suitable breeding grounds. Their migration patterns, while not fully understood, are crucial to understanding their life cycle and behavior in the wild.
Despite their widespread distribution, the ocean sunfish is a relatively rare sight due to their preference for the deeper parts of the ocean.
However, thanks to their distinctive size and appearance, they are often spotted by fishermen, divers, and oceanographers conducting research in coastal regions.
Unique Characteristics of the Ocean Sunfish
The ocean sunfish is an extraordinary animal with several unique features that set it apart from other marine life. Its most distinctive trait is its body shape: a large, flat, round form that makes it look like a giant pancake or moon. This shape, combined with its lack of tail fin, gives the ocean sunfish a streamlined, yet unusual, appearance.
Another fascinating feature of the ocean sunfish is its remarkable size.
As one of the largest bony fish, it can weigh as much as 2,000 kilograms. Despite this, the fish feeds mainly on jellyfish, a delicacy that provides the necessary nutrients to sustain its enormous body.
The ocean sunfish’s ability to thrive on a diet consisting almost entirely of jellyfish is a testament to its adaptability and unique place in the marine food chain.
Additionally, the ocean sunfish is a creature of immense resilience.
It has a tough, almost leathery skin that protects it from predators, including larger sharks. However, despite its imposing size, the ocean sunfish is often seen with large bite marks on its body, a sign that it is regularly visited by sea creatures like cleaner fish, which help remove parasites and dead skin.
