The ocean sunfish, known for its massive size and parasite-covered body, is explored in-depth by Sarika Cullis-Suzuki in the documentary series “The Nature of Things 101.” This peculiar fish, the Mola mola, defies typical fish characteristics with its circular body, lack of a tail, and oversized fins.
Cullis-Suzuki showcases the unique features of the ocean sunfish, highlighting its ability to travel long distances at significant depths multiple times a day in search of food. Despite their slow movement and large surface area, these fish attract numerous parasites that inhabit various parts of their bodies, including the skin, gills, fins, eyeballs, mouth, and intestine.
With scientists identifying 73 different parasite species on the Mola mola and other ocean sunfish types, the extent of parasitic infestation is staggering. Some parasites even have their parasites. To combat this, the sunfish resort to breaching behavior, leaping out of the water and crashing back down, possibly to dislodge parasites. They also allow smaller fish and birds to feed on the parasites as a form of natural pest control.
Despite the knowledge accumulated about the ocean sunfish, there remains much to uncover about this enigmatic species. Cullis-Suzuki emphasizes the necessity for further research and understanding of these fascinating creatures.
