AN IDENTIFICATION SYSTEM FOR COMMON DEMOSPONGIAE OF THE SÃO SEBASTIÃO CHANNEL AREA, SW ATLANTIC, DEVELOPED WITH THE LINNAEUS II SOFTWARE

Resumen

Created for the management of data in multimedia, the software Linnaeus II has been used here for the preparation of a CD-ROM with a main objective: a tool for the identification of Porifera. Twenty-five species among the most conspicuous occurring in the São Sebastião Channel area were selected. For each species it is supplied: a description of the external and internal morphology, ecology, literature, list of specimens in the collection of the Museu Nacional/UFRJ and distribution in the São Sebastião Channel, in Brazil and in the world. A key for the identification of these species was elaborated allowing to start at different levels, depending on a greater or smaller familiarity of the user with one or another type of character (i.e.: color, form, consistency, spiculation).
