Oh there are actually about 50,000 known species of mite and probably over a million unnamed species of mite on Earth, JUST SOME of which include:
The typical parasitic, tiny skin mites that infest reptiles, birds and mammals
Ticks, which are in fact the largest of all mites
Mites that only suck the fluids of other bugs
Nicer mites that just clean the skin of their hosts, including many bird feather mites and microscopic mites living in our eyelash follicles
The dust mites found in all houses that only eat our old skin flakes
Mites that only eat rotten meat and all just ride around on top of flies or beetles to get there
Predatory mites that hunt other things around their size
Plankton-feeding water mites
Mites we’ve documented and named but still don’t know what they eat
Long worm-shaped mites that swim through searing hot desert sand and we don’t know exactly what they’re eating
Mites that live in special mite-carrying pockets on the backs of some wasps and protect the wasp’s eggs from other parasites
Mites that only live inside of stink bug stink glands, eating their stink juice
Mites that only live in and eat the intestines of sea urchins
Mites that only live on the eyeballs of fruit bats eating eye secretions
Mites that only live in the noses of walruses eating mucus
Mites that only live inside of turtle anuses eating turtle poop
Mites that only live in the noses of hummingbirds but only mate in flowers so when the hummingbird stops for a drink the mites jump out of its nostrils and run down the beak at speeds relatively exceeding a cheetah
A mite that only lives on the end of an army ant’s leg after removing the army ant’s foot but it’s okay because the ant can use the mite as a possibly even better foot
A mite that only lives in the left ear of one kind of moth, and only the left, because if they lived in both ears the moth wouldn’t be able to hear a bat coming which would eat the mites along with the moth
