Big Idea 1: Term 14

Chordate: The main distinguishing characteristics of chordates are
that each one has a notochord (for support), a dorsal nerve cord
(spinal cord), pharyngeal slits (gills), and a tail at some point his life.
I, like all humans, am a chordate. Note: My apologies for the multiple
dog pictures previously posted. Ignore the coonhound one.
