Muddiest Point

My muddiest point in this unit was understanding the difference between the 3 groups of fish: Agnatha, Chondrichthyes, and Osteichthyes. Thanks!

    Differences in characteristics are easy ways to remember the difference between these 3 groups.
    - Agnatha: JAWLESS FISH
    -Chondrichthyes: "CARTILAGINOUS" OR LACK BONE examples include sharks or rays...
    -Osteichthyes: Made up of "TRUE BONE" and examples would include rainbow trout or coelacanth.
