The ocean sunfish, despite its name, may not align with the typical image of a fish. Weighing up to two tonnes and adorned with parasites, including on its eyeballs, this unique creature is the subject of exploration in a recent episode of “The Nature of Things 101” hosted by Sarika Cullis-Suzuki.
Cullis-Suzuki highlights the distinctive features of the Mola mola, a type of ocean sunfish that stands out as one of the largest fish in the ocean. With its circular body, lack of a tail, and massive fins, the Mola mola challenges traditional fish stereotypes.
The ocean sunfish, known for its extensive travels deep into the ocean to search for food, faces a challenge due to its slow movement and large surface area, making it a magnet for parasites. Researchers have identified a staggering 73 different parasite species on the Mola mola and other ocean sunfish variants, some of which have parasites of their own.
To combat these parasites, the sunfish employs various strategies, including breaching out of the water and allowing smaller fish and birds to feed on the parasites infesting them. Despite the existing knowledge about these creatures, there remains much to uncover about the behaviors and biology of the ocean sunfish.
Cullis-Suzuki emphasizes the need for further research to deepen our understanding of this fascinating species. For more insights, viewers can tune in to “The Nature of Things 101” on CBC Gem or visit The Nature of Things YouTube channel.
