This site, unique for marine planktonic copepods, and created by the Laboratoire Arago (Observatoire Océanologique de Banyuls sur Mer), is the fruit of more than 30 years of research coordinated by Claude Razouls on copepods and multiple collaborations at the international level. It presents a complete interactive database of all described marine planktonic copepods from the entire globe, including:
- Taxonomic classification with references
- Illustrated and referenced species database
- A geographic distribution in the world's oceans and seas, with division in zones and subzones
It comprises 335 genera, and 2573 studied species with geographic distribution.
