Discover new layers of fish in the gut

According to a new discovery by Canadian biologist Claire Healy, the gut is the "happy settling place" of hundreds of species of organisms.

Healy named the newly discovered class of Rhinebothriidea. This biologist has discovered about 200 species of flukes above and hundreds of other species are waiting to be identified.

Healy has done a lot of special research on parasites living in parasites in shark intestines and stingrays and says every fish studied has flukes, some have hundreds of flukes in them and they belonging to about 20 species, some of them are less than 1 cm in size but have lengths of up to 20 cm.

Claire Healy was not the first to discover flukes, but she was the first to find that there were many species of flukes enough to put them into a new class of organisms. Flukes can live in the intestines of any vertebrate organism, including humans, and absorb the nutrients of that host.

The biological world is classified into many levels with names such as species, breeds, families . A class of organisms is a large group of many species, such as from coniferous trees, to shrubs as a class , predators from wolves to lions or mink belong to one class. So finding a new class of organisms is extremely rare.
