Identification of organisms is an important item when it comes to nominating images for one of the valuation processes on Commons. Of course we can not all be biologists and even the latter have their own specializations. This page aims at providing links and other means of support to those who want to know what organism exactly they have captured on their photograph.
Here you can compare your picture with pictures on the internet. Beware, this is not an infallible method.

For specific groups it is hard to find information on the internet or in libraries. A proven solution is to look up a taxonomist via the internet and send him/her the picture concerned together with location and date. This is particularly handy when dealing with insects.
