Asterzoa is a diverse superphylum of Carpozoan fauna. Ancestrally resembling a starfish with only four arms, they have branched into a variety of forms, including active bilateral predators, sessile cnidarian-like filter feeders, and leaf-like photosynthesizers. They have notably modified the "bait" feature ancestral to carpotestans for a great variety of different uses, including filter-feeding, sensory purposes, and even locomotion.
