Introduction to iSpot Bayesian keys

We have produced a number of interactive keys to help you with identification. For southern African keys click here

The iSpot Bayesian keys are a novel form of key that may be different from other keys that you have encountered.

Unlike a traditional branching key, you don't have to answer questions in a fixed order. Simply describe your specimen using as many characters as you can, and the computer will sort through the list of species it knows about and suggest which is most likely. When a species is starred, you have a good match - check the description to confirm your identification. Our keys use probabilities: simply, the more evidence you can provide, the more definite your identification will be.

For more information, read our help page on using iSpot Bayesian keys.
