The remaining animals, the great the greater part—comprising some 29 phyla and above a million species—sort the Bilateria clade, which have a bilaterally symmetric overall body program. The Bilateria are triploblastic, with three very well-created germ levels, and their tissues kind distinctive organs. The digestive chamber has two openings, a mouth and an anus, and during the Nephrozoa You can find an inner system cavity, a coelom or pseudocoelom.
