2) Watch the short introduction video to familiarize yourself with a few Anolislizards.

3) Click the “Ecomorph” Module on the top left and follow the instructions. Note, the “add label” button is on the top right, so don’t cover it with lizards otherwise you can’t add additional labels!

4) Measure your lizards carefully following the provided instructions. Graph your data and answer the questions at the end of the module.

9) Repeat step 8, but use the Islands the lizards are from, rather than Ecomorph.
