About AlgaeBase

What is AlgaeBase?

AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms. For the convenience of marine botanists, we have included the sea-grasses (about 100 species), even though they are flowering plants.

Copyright and Intellectual Copyright

Copyright and other intellectual property rights worldwide to the design and structure of the database and its web interface are claimed by AlgaeBase.

Funding and sponsorship

The Phycological Society of America, the British Phycological Society, the International Phycological Society, the Japanese Phycological Society, and the Korean Phycological Society kindly subvent AlgaeBase annually and AlgaeBase licenses its data to other websites and organisations to support its activities.


Many organisations and people have, funded supported and contributed to AlgaeBase since its small beginnings on 20 March 1996. A full list can be found here.

We particularly appreciate the immense support of Dr J.A. West and Dr P.W. Gabrielson.


Programming is by Pier Kuipers. Jonathan Guthrie, Caoilte Guiry, and Michael Guiry were instrumental in programming earlier versions of the system.

AlgaeBase is often a compromise of taxonomic opinions that may or may not reflect your particular conclusions. It is also a work in progress, and is thus incomplete. Please note that AlgaeBase is purely meant as an aid to taxonomic studies and not a definitive source in its own right. You should always check the information included prior to use.
