In a fascinating exploration of the ocean sunfish, host Sarika Cullis-Suzuki delves into the peculiar characteristics of this massive creature in a recent episode of The Nature of Things 101. Despite its unconventional appearance, including a circular body, lack of a tail, and enormous fins, the Mola mola remains one of the largest fish in the sea.
Known for their extensive travels, these fish navigate deep waters multiple times a day in search of food. However, their slow movement and large surface area make them susceptible to various parasites that inhabit different parts of their bodies, from the skin to the eyeballs and even the intestines. Scientists have identified a staggering 73 different parasite species on the Mola mola and other ocean sunfish varieties, some of which have parasites of their own.
To combat these pesky hitchhikers, the sunfish employ unique tactics such as breaching, where they leap out of the water and crash back down, potentially dislodging parasites in the process. Additionally, they allow smaller fish and birds to feast on the parasites infesting them.
Despite our current knowledge of the ocean sunfish, there is still much to uncover about this enigmatic species. Cullis-Suzuki emphasizes the need for further research to deepen our understanding of these fascinating creatures.
