A Global Species Database (GSD) is a digital catalog of organisms often defined around a conservation purpose for the organisms of interest. GSDs attempt to be globally inclusive of species within their inclusion parameters versus local species databases. GSDs have a defined purpose, is a GSD for economically valuable fish species, while FishBase focuses on fin fish regardless of their human potential for exploitation. Attempts have been made to create GSDs for extinct species such as trilobites. A GSD can be broad in taxonomic scope, such as AlgaeBase comprehensively including algae and seagrasses from the entire planet, or narrow such as , a GSD for members of a single plant family, the Fabaceae.
