Algaebase aspires to include all organisms regarded as algae, including the Cyanophyta (or Cyanobacteria). Primarily a taxonomic database, it has diverse information on freshwater, marine (seaweeds) and terrestrial algae, including uses and many pictures. Seagrasses are also included for the present. About 55,000 names are currently documented. AlgaeBase was developed at the Martin Ryan Institute, National University of Ireland, Galway, with support from the Higher Education Authority (Irish Department of Education and Science) and the European Commission.
