Vertebrate Ancestors: 'Chordate' Origins, 'Vertebrae and 'Cephalization Who are the vertebrates? How many species? - "animals with backbones" - phylum chordata: --> notochord, segmentation, jointed appendages (via deutersotome development and endoskeleton, derived from coelom, body cavity and bilateral symmetry) - subphylum craniata --> have no column hyperoterti (notochord) - roughly 45'000 species - infraphylum vertebrata --> 42'000 species (5% life - less diverse/...

1. Phylum Porifera - Answer-- sponges - loosely organized and lack tissues - multicellular with several types of cells - 8,000 species, mostly marine - no apparent symmetry - adults sessile, larvae free-swimming - water drawn through pores into spongocoel - flows out through osculum - choanocytes line spongocoel - mesohyl between choanocytes and epithelial cells - reproduce sexually and asexually 10. Phylum Nematoda - Answer-- roundwomrs - in nearly all habitats - over 20,000 specie...
