Echiniscoididae

The Echiniscoididae are a family of tardigrades, water-dwelling, eight-legged, segmented micro-animals. It is one of the four families in the Echiniscoidea order.

Echiniscoides is a genus of tardigrades in the family Echiniscoididae. It was named and described by Ludwig Hermann Plate in 1888.

Anisonyches is a genus of tardigrades in the family Echiniscoididae. The genus was first described and named by Leland W. Pollock in 1975. The genus name is a combination of the Greek aniso ("unequal") and onyches ("claws"), since Anisonyches have four claws each on the first three pairs of legs and three claws each on the fourth pair of legs.
