FishBase is a global biodiversity information system on finfishes. From its initial goal to provide key facts on population dynamics for 200 major commercial species, FishBase has now grown to having a wide range of information on all species currently known in the world: taxonomy, biology, trophic ecology, life history, and uses, as well as historical data reaching back to 250 years.

At present, FishBase covers >35,600 fish species compiled from >61,700 references in partnership with 2,520 collaborators, >329,500 common names and >64,000 pictures. Our website gathers more than 700,000 visits monthly.

The World Ocean Database (WOD) is world's largest collection of uniformly formatted, quality controlled, publicly available ocean profile data. It is a powerful tool for oceanographic, climatic, and environmental research, and the end result of more than 20 years of coordinated efforts to incorporate data from institutions, agencies, individual researchers, and data recovery initiatives into a single database. WOD data spans from Captain Cook's 1772 voyage to the contemporary Argo period, making it a valuable resource for long term and historical ocean climate analysis. Original versions of the 20,000+ datasets in the WOD are available through the NCEI archives.
