Ichthyology scavenger hunt #w4112

I try hard to make my classes interesting. Part of that is finding new and hopefully innovative ways to get students thinking about systematics, taxonomy and conservation. To that end we are having a scavenger hunt at the American Museum of Natural History which will serve as a quiz for my Ichthyology quiz.

As all the students have smart phones they’re going to be tweeting me the answers using the hashtag #w4112. In case any of you want to follow along in the twitter-sphere I now present the quiz:
