A Dichotomous what??


Are you still having trouble understanding dichotomous keys? If you need extra practice, try to identify the microscopic organisms found in the Chesapeake Bay.

  3. Speaking of the Chesapeake Bay, I took a three week bay ecology course with Johns Hopkins over the Summer. It was in Maryland, so we studied the Chesapeake Bay and went on trips three times a week. We used one really huge dichotomous key to identify all the the fish. It was really fun.

  9. I'm kind of confused with the dichotomous key. Remember the one that we did, not the leaves or the crazy people one, or the fish one. It was some other one, I don't know what though, but sometimes i don't get if you're doing the first picture, do you look at the 1st bracket? and then the second with the second??

    I LOVE THIS BLOG, but I'm a little confuzzled...

  10. Hey Ryan - Always start with the first bracket or step. It doesn't matter what organism you are trying to identify:) Does anyone else have helpful tips on using dichotomous keys?

  12. When you try to solve a dichotomous key you can keep one finger on the organism and check if it fits or does not fit. Also check off answers you already used.

  13. I totally agree with what Rachel said Leslie. You do really rock and this blog is so cool!! I can really learn a lot from this!
    Also, for solving dichotomous keys, if you take your time to figure things out, it will actually be a lot easier.
