3 Characteristics -(at some point in their development)
3 Characteristics 1- Nerve cord – hollow tube near back

8 Groups of Chordates
6 Groups of Ectotherms “coldblooded” body temp. = outside temp.
8 Groups of Chordates 2 Groups of Endotherms “warmblooded” body temp. = constant
Fish Water-dwelling vertebrates that have: 1- scales 2- fins 3- gills
3 main groups of fish 1- jawless – primitive, lack jaws (ex. Lamprey + hagfish)
3 main groups of fish 2- cartilaginous – no “bones” Skeletons made of cartilage (ex. Sharks & rays)
3 main groups of fish 2- cartilaginous – no “bones” Skeletons made of cartilage (ex. Sharks & rays) Sharks reproduce internally and must move gill slits to breathe
3 main groups of fish 3- bony – skeletons of bone (ex. Trout & perch) * also have swim bladders
