Ocean Sunfish: The Giant, Parasite-Covered Oddity
2 Oct
Summary
- The ocean sunfish, or Mola mola, is one of the world's largest and strangest fish.
- These slow-moving giants host an astonishing number of parasites on their bodies.
- Sunfish use breaching and allowing smaller creatures to eat parasites for removal.
The ocean sunfish, specifically the Mola mola, stands out as one of the largest and most peculiar fish in the sea. Its appearance is quite distinct, featuring a large, circular body and lacking a tail, making it a stark contrast to typical fish shapes. These creatures undertake significant daily journeys, diving hundreds of meters deep in search of sustenance.
However, their expansive surface area and slow swimming speed make them particularly vulnerable to parasites. Researchers have documented an extensive variety of parasites, noting up to 73 different species that infest the sunfish. These parasites can be found on nearly every part of the fish's body, including its eyes.
To manage this parasitic load, ocean sunfish employ remarkable behaviors. One observed method involves breaching, where the fish leaps out of the water and crashes back down, potentially dislodging parasites. They also rely on symbiotic relationships, allowing smaller fish and birds to feed on the parasites, a fascinating adaptation for survival.
