Scientists Find New Species Living in Whale Shark's Gills gizmodo.com

Japanese scientists have discovered a new species of crustacean in the gills of a shark, according to a recent paper.
This is the first one found on a whale shark, the largest fish species in the ocean.
AdvertisementScientists sampled the whale shark’s gills with a suction pump while scuba diving in an underwater fish preserve off of Okinawa in 2017.
Not only to these amphipods swarm sharks, but apparently similar species will swarm other creatures that enter their space, like human scuba divers.
But whether the species is actually associated with whale sharks or whether it was merely a local species opportunistically feeding remains to be seen.
