2. Since you guess that the animal in front of you is a reptile, you click on “REPTILES”.

3. Next, you will see a list of reptile groups, each represented by a characteristic shape. The animal you are looking at looks like a lizard. You select “Lizards”.

4. A list of lizards with thumbnails pops up. Browse the list and select the animal that looks similar to the one you are looking at.

5. The species plate shows common and scientific names, size of the animal and its natural history in form of icons at the bottom of the plate. Icon legend can be called out by tapping on any of the icons.

6. Browse the species’ photos by swiping your finger. There are up to 5 photos per species. All photos come with a photographer’s credit, captions may also be included. Use the magnifying glass icon to view a full screen version of a photo. Use < button to go back.

Doesn't work

I am running iOS 9.1. Installed this app and haven't been able to use it. It crashes every time I run it on both my iPad and iPhone. I will be asking for a refund.
