This site is a source of general information on all aspects of seaweeds. Seaweeds are marine algae: saltwater-dwelling, simple organisms that fall into the rather outdated general category of "plants". Most of them are the green (1200 species), brown (2000 species) or red (6000 species). [Information of the supplier]
AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms. At present, the data for the marine algae, particularly seaweeds, are the most complete. Initially set up in 1996 as an attempt to list all the known species of seaweeds in the world and their nomenclatural authorities, it has been expanded to include other sources (literature references) nomenclatural information (including types), synonyms (often annotated), pictures (over 1,000, mainly seaweeds), and common names (over 2,500). ...

The INA is a card file maintained by Paul Silva at the Herbarium of the University of California. It contains nearly 200,000 names of algae (in the broad sense). Most names are available only as images of the cards (...) which are available through indexes that are being made gradually, with the help of users. Indexes to many genera have been completed. The "Bibliographia Phycologica Universalis" (BPU) is a card file containing bibliographic references pertaining to algal taxonomy. ... [Information of the supplier, modified]
The Phycology.Net aims to provide online data on the biodiversity of algae, especially their taxonomy, distribution, phylogeny, descriptive characters, collections, literature etc.; inform about phycological institutions, journals, databases (link sections) and persons engaged in phycology; facilitate interaction between databases and support the development of standards for data exchange; reach scientists all over the world and invite them to use the platform and to help improving the quality and quantity of data; maintain a discussion forum for phycological subjects and the further development of the platform itself. ...

The AlgaTerra Database is a comprehensive information system on biodiversity of terrestrial and limnic Micro Algae including a database, integrating taxon, type, name and collection data as well as ecological and molecular information. The AlgaTerra mission is to provide referenced data for fundamental research, applied research, teaching, and the public. ... [Information of the supplier, modified]
Algae are photosynthetic organisms that occur in most habitats. They vary from small, single-celled forms to complex multicellular forms, such as the giant kelps that grow to 65 meters in length. The Algal Collection of the U.S. National Herbarium is represented by nearly 300,000 accessioned and inventoried herbarium specimens preserved on herbarium sheets, microscope slides or liquid preparations. The collection is comprised of marine, estuarine, freshwater, terrestrial (including cave) and airborne algae and is worldwide in origin, with strong representation of tropical and subtropical marine algae. ...

Corallines are a highly complicated group. The identification of fossil coralline algae bears several problems and the intraspecific variability is very high. Their distribution is very wide spread: Corallines occur from the tropics to polar regions, and from the intertidal down to more than 200 m water depth. The current homepage aims to make this algal group more popular. After an introduction, different growth forms in fossil and present-day corallines are demonstrated. One of the main topics is a comprehensive comparison of fossil and present-day taxonomical features. Moreover, descriptions of corallines from Austria, Italy and the Northern Red Sea are presented. Finally, you can find a list of the described taxa. ... [Information of the supplier, modified]
The purpose of this website is to provide a research and teaching resource for students, teachers and researchers interested in the group of protists commonly known as, the euglenoids. The general features of the group and examples of cellular organization are provided. The classification systems used to separate these protists into definable groups are shown along with interactive keys which can be used to identify organisms to genus or species. The evolutionary relationships among euglenoids, and between euglenoids and other protists are presented in Phylogeny. If you are searching for information on a specific euglenoid, an alphabetical listing of taxa is provided to assist you. The dynamic nature of swimming, wriggling and eating in euglenoids is dramatic. Movies have been provided to illustrate these dynamic processes, many of which characterize certain types of euglenoids. ... [Information of the supplier]
The images are of representative taxa in various algal groups. New images are added periodically throughout the year and on a more frequent basis during April-June. Use of the images by others for educational purposes is welcome, but before use please send an email to Dr. Morgan Vis in order to inform her of your plans. ... [Information of the supplier]
