You will need to decide the next characteristic that will divide the four remaining fish into two groups. Then, continue to choose characteristics that will separate that group into smaller groups. Write your key in the lines provided. Dichotomous Key: 1. A. Fish with long, tube-like body……………………..……………Family Sandvigidae B. Fish with body shape not tube-like…………………………Go to statement ______ 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
