  • Deuterostomes

    forms the mouth after the anus

  • Tripoblastic

    Phylum Chordata germ layers

  • Coelomate

    With fluid-filled cavity between the gut and the outer body wall

  • Notochord, Dorsal, tubular nerve chord, Pharyngeal gills, Post anal tail

    key features of Chordates

  • Notochord

    a dorsal longitudinal rod, supports the body in Chordates

  • Dorsal, tubular nerve chord

    brain and spinal cord (fish & other vertebrates)

  • Pharyngeal gills slit

    slits - openings in the pharynx that extend to the outside environment in Chordates

  • Post anal tail

    appendage that extends posterior to the anus.

  • Subphylum Urochordata

    tunicates subphylum

  • Subphylum Cephalochordata

    Translucent, fish-shaped animals, 5 to 10 cm long and pointed at both ends

  • Larval form

    form of Urochordata that possess all key feature of Chordates

  • Subphylum Cephalochordata

    All 4 chordate features are well represented throughout the adult life, examples of this subphylum is the Lancelet

  • Subphylum Vertebrata

    w/ bony or cartilaginous backbone (vertebrae) w/c surrounds the nerve cord

  • Tail

    situated behind the anus of Vertebrata

  • Superclass Agnatha

    w/o true jaws or paired appendages

  • Class Myxini

    class under the subphylum vertebrata, supercalss agnatha

  • Class Myxini

    Mouth w/ 4 pairs of tentacles; 5-15 pairs of gill pouches; slime glands; notochord persist all through out life & not replaced by vertebral column

  • Hagfish

    example of class myxini

  • Class Cephalaspidomorphi

    Suctorial mouth w/ horny teeth; 7 pairs of gill pouches;

  • Lampreys

    example of Class Cephalaspidomorphi

  • Superclass Gnathostomata

    jawed fishes (w/ jaws) and all tetrapods (4-limbed); paired appendages

  • CLASS CHONDRICHTHYES

    ▪ Streamlined body w/ heterocercal tail; ▪ Cartilaginous skeleton; ▪ 5-7 gills w/ separate openings, no operculum, no swimbladder

  • Heterocercal tail

    class chondrichthyes tail

  • Class Osteichthyes

    ▪ Primitively fusiform body; ▪ Ossified/BONY skeleton; ▪ Single gill opening on each side w/ operculum; ▪ Swim bladder (bouyancy) or lung present

  • Amphibians

    • Live on land and water • Webbed feet • Breathe with lungs and gills • Cold-blooded animals • Moist smooth skin (No hair or fur) • 4 legs (sometimes none) • Lay many eggs

  • Reptiles

    • Have scales (not fur) • Dry skin • Usually lay eggs or live young • Ear holes instead of ears • 4 legs or none • Cold-blooded

  • Birds

    Have feathers and wings • Lay eggs • Have 2 legs • Ear holes instead of ears • Warm- blooded
