Welcome to this computer assisted guide to zooplankton and micronekton of the North Sea.

The North Sea Zooplankton project was initiated by ETI and the Zoological Museum of the University of Amsterdam. This first CD-ROM contains pictorial keys, text keys and a database with descriptions, illustrations and literature references for about 470 species of zooplankton (> 1mm) and micronekton in the North Sea. 
Major groups involved are the Medusae, Siphonophora, Ctenophora, Chaetognatha, planktonic Tunicata and Polychaeta, pelagic Gastropoda, Cephalopoda, and a vast group of planktonic Crustacea — with the exclusion of copepods and larvae of other crustaceans, polychaetes and fish.
