Bilateria - Wikipedia
WEBBilateria (/ ˌbaɪləˈtɪəriə / BY-lə-TEER-ee-ə) [2] is a large clade or infrakingdom of animals called bilaterians (/ ˌbaɪləˈtɪəriən / BY-lə-TEER-ee-ən), [3] characterized by bilateral symmetry (i.e. having a left and a right side that are mirror images of each other) during embryonic development.
Bilateria - Simple English Wikipedia, the free encyclopedia
WEBThe Bilateria are animals which are bilaterally symmetrical. They have front and a back end, an upside and downside, and a left and right side. Most animals are bilateral.
List of bilaterian orders - Wikipedia
WEBList of bilaterian orders. The relative number of species contributed to the total by each phylum of animals. Arthropoda is the phylum with the most individual organisms. Bilateria is an extremely diverse group of animals containing a vast majority of its species, largely due to the enormous amount of arthropods.
Nephrozoa - Wikipedia
WEBNephrozoa. Nephrozoa is a proposed major clade of bilaterian animals. It includes all bilaterians other than Xenacoelomorpha. It contrasts with the Xenambulacraria hypothesis, which instead posits that Xenacoelomorpha is most closely related to Ambulacraria. [1][2][3][4][5] Which hypothesis is correct is controversial.

WEBBilaterally symmetrical animals comprise the overwhelming majority of metazoan species. Bilaterality evolved once, early in the evolution of the clade known as Bilateria. The driving force for bilaterality was probably the evolution of active locomotion in search of food.
