Phreatoicidea

Reiner Richter cc-by-nc-sa-4.0

Phreatoicidea is a suborder of isopods. There are 84 species of Phreatoicidea, in 31 genera and 6 families. This suborder has been around since the guadalupian epoch. It includes groups like Hypsimetopidae, Ponderellidae, and Phreatoicopsidae. They rely on drag powered swimming to move around.

URI: https://eol.org/schema/terms/drag_based_swimming
Definition: Drag swimmers use a cyclic motion where they push water back in a power stroke, and return their limb forward in the return or recovery stroke. When they push water directly backwards, this moves their body forward, but as they return their limbs to the starting position, they push water forward, which will thus pull them back to some degree, and so opposes the direction that the body is heading. This opposing force is called drag. The return-stroke drag causes drag swimmers to employ different strategies than lift swimmers. Reducing drag on the return stroke is essential for optimizing efficiency.
