[[File:Extant.jpg|right]]'''Asterzalia''' is the most primitive [[Asterzoa|asterzoan]] phylum, yet ironically the most "advanced" in terms of intelligence and lifestyle. All extant members have four arms (one of which is modified for waste disposal), a nervous system, chemoreceptive skin patches, and the ability to swim. Though they ancestrally had four-point radial symmetry, some have evolved bilateral symmetry by differentiating their arms as they mature; all bilateral species, particularly those within Lagnodactylia, have radially symmetric larval or embryonic stages.
