In the realm of marine life, a creature known as the ocean sunfish defies expectations by reaching weights of up to two tonnes and sporting parasites that even invade its eyeballs. Host Sarika Cullis-Suzuki explores the eccentricities of this fish species in a detailed analysis on The Nature of Things 101.
Cullis-Suzuki expresses admiration for the ocean sunfish’s unconventional appearance, highlighting its circular body, lack of a tail, and massive fins. Utilizing a life-sized model, she educates co-host Anthony Morgan on the unique features of the Mola mola, an ocean sunfish variety renowned for its size.
These ocean sunfish undertake extensive journeys, diving hundreds of meters deep multiple times daily in search of sustenance. However, their leisurely pace, large body surface, and passage through diverse water layers make them susceptible to parasitic infestations.
Researchers have identified a staggering 73 different parasite species residing on the Mola mola and similar ocean sunfish types, some of which host parasites of their own. To combat these intruders, these sunfish exhibit peculiar behaviors such as breaching out of the water and crashing back down, possibly to shake off parasites. Additionally, they permit smaller fish and birds to consume the parasites.
Despite the wealth of knowledge amassed about the ocean sunfish, further research remains imperative to fully understand this enigmatic species. Cullis-Suzuki emphasizes the ongoing need for exploration and study to unravel more mysteries surrounding these fascinating creatures.
