Welcome to LUMCON's
Guide to Phytoplankton (including Harmful Algae) from Louisiana Estuarine and Coastal Waters

An online taxonomic guide

This Guide is designed both for those needing help in identifying phytoplankton species, as well as experienced taxonomists. It offers several avenues to find a particular species of interest. Once your species of interest is located, you will be taken to an Organism page that lists taxonomic details about that species. Clicking on a photo on that page will navigate you to a full size image and collection data for that photograph.

The taxonomic information in this Guide was compiled from several published sources (References), as well as observations of the LUMCON Phytoplankton Group. Click Here for the Scope of the information within the Guide.
