Pseudorhabdosynochus buitoe is a small parasitic flatworm. It lives on the gills of marine fish and feeds on their tissues.
Pseudorhabdosynochus buitoe differs from other species of the genus by the special structure of the copulatory organ. It regulates the number of fish in the seas and serves as part of the natural balance.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
