This site offers an enormous collection of photographs of wild species and natural history objects. It covers most groups of organisms with the exception of birds and other vertebrates. The photographs are presented to illustrate biodiversity and as an aid to identification. The criterion for inclusion of a species is that it must have been, or might be expected to be, found in Britain or Ireland. BioImages follows the biological classification. Biota is a hierarchical system with species grouped in genera, genera in families, families in orders and so on up to kingdoms and superkingdoms. The datasets are linked to bioinfo: food webs and species interactions in the Biodiversity of UK and Ireland.
