The Tardigrada Phylum is split into Classes. One Class is listed below:
Heterotardigrata Class: Includes certain species of Water Bears.
The class above is split into smaller groups, called Orders. Orders are then split into Families, and Families are split into Genera. Remember, as each group gets smaller, organisms in that group are more and more alike. Each Genus will contain individual Species.
Information on specific Orders and Families for the Heterotardigrata Class is not included on this website, but you can find out which groups a species belongs to by checking the Classification Box at the bottom of each Species Page. See the example of a Water Bear below:
