blade like bodies that exhibit all for characteristics of chordates as an adult Sub phylum: Cephalochordata
Lanclets are examples of.. Cephalochordata
sessile marine animals as adults only has one chordate characteristic, free swimming as larvae and have all four chordate characteristics sub phylum: Urochrodata
turnicates and sea squirts are examples of urochordata
have notochords, dorsal hallow nerve chord, gill slits, and post anal tail chordate characteristics
composed of fibrous tissue, longitudinal flexible rod located between digestive tube and nerve chord Notochord
develops from ectoderm line that rolls into dorsal to notochord develops into brain and spinal cord usually solid and located ventrally dorsal hallow nerve cord
regional posterior to mouth aka pharynx develops into slits that open to outside body allow water to enter via mouth and exit without passing through the digestive tract used for gas exchange (aquatic vertebrates) develops into ear (terrestrial) gill slits
tail extends posterior to the anus lost usually during embryonic development post anal tail

used for gas exchange Chorion
stores metabolic waster Allantois
fluid filled surrounds embryo and provided protection Amnion
nutrients to developing embryo Yolk Sac
chorion, allantois, amnion, and yolk sac are what the four membranes that make up ammonites
exothermic presence of scales for protection big diversity Class: Reptillia
Adaptations that facilitate flight bones are "honey comb" shaped toothless but has a beak forelimbs are wings high metabolism endothermic efficient respiratory and circulatory systems class: Aves
survived the KT extinction mammory glands hair layer of fat under skin retains body heat specialized teeth Class: Mammalia
