Document Summary

Are more closely related to other chordates than to lancelets. Their most apparent chordate characters are during larval stage that lasts only minutes. It undergoes radical metamorphosis, and many of its chordate characteristics disappear, organs rotate 90 degrees. Draws water through siphon, it passes through pharyngeal slits, then into a champer called atrium and exists through siphon again. Food particles are ltered by mucous net and transported by cilia to esophagus. When attached they shoot water through siphon. 34. 2 - vertebrates are chordates that have a backbone. Vertebrates have characteristics that distinguish them from other chordate. These characters are results of gene duplication, they have two or more sets of hoxgenes. They have skull and have a backbone made of vertebrae, this is instead of a notochord. They are the only vertebrates that lack jaws. They are classi ed as vertebrae due to the rudimentary vertebrae, which has only cartilage. The clade of jawless vertabrades is called cyclostomes.
