Tachypodia (lit. "fast feet") are a clade of zooplankton Polypodia.
Tachypodia are zooplankton, living near the ocean surface. They appear to be largely herbivorous, feeding on phytoplankton and chemoplankton. Tachypodys themselves form a large basis of the oceanic food chain, being prey to Gastrozoa larvae and filter feeders such as Ptilopods and Isopterygians.
While they are not elaborated upon, there are thousands of species of Tachypods.
Having undergone similar tagmosis to the Acanthopods, Tachypods have an anterior tagma consisting of four feeding limbs lined with setae. Their middle tagma is dedicated to locomotion, consisting of three pairs of wide fins (also lined with setae), used by the Tachypods to adjust their position in the water. Their posterior section houses both an enlarged gill surface and their reproductive organs.
Tachypods have high reproduction rates, their only true defense against extinction.
