Nudibranchs and Sea Slugs are a favorite of SCUBA divers and underwater photographers. They come in dozens of interesting colors and shapes and are easy to find and photograph.

Nudibranch Wizard is an App that helps divers and Underwater Photographers identify Nudibranch and Sea Slugs. It features two different ways to search for the identity of a Nudibranch. You can search by name by simply typing in a portion of the Genus or species name that you are looking for. If you aren't sure what the name might be, you can search by selecting Descriptors for Body Type, Primary Color, Secondary Colors and a number of other attributes. For example, you could search for "External Gills", "Smooth Body", "White Primary Color" and "Black Lines" to get a selection of Nudibranchs that match those descriptors. The App initially comes with a built in Database of 100 Nudibranchs that are commonly seen in the tropical Indo-Pacific.

The App also includes a Nudibranch name ID game that makes learning Nudibranchs fun. You get points for correctly identifying Nudibranchs.

Good base

Common names needed - as that's what divers use for ID primarily.

Needs some more work but not bad

Common names, more common undies, flatworms, more descriptions are needed.
