What is the Species Diversity of a Cave?

You may think that there is not much in caves but a lot of crickets and spiders. Or, that maybe there are a lot of bats and not much insect or other life? Caves are inhabited by lots of different kinds of creatures. From 973 species of cave organisms in the U.S. , Dr Cave Facts tells us that from reading more of the paper by Christman and Culver that there are:

210 genera
96 families
38 orders

of the following species:

Turbellaria (free-living flatworms)


Oligochaeta (worms to you, in particular, segmented worms such as earthworms)

Are you impressed? Or, are you wondering why scientists use all those many-syllable words to name things.
