(DEscriptive Language for TAxonomy) is a windows based
taxonomic database that stores morphological data and illustrations
and then, among other things, makes them available in the
form of natural language descriptions, illustrated interactive
keys, and as output for phylogenetic analyses.
(www.crustacea.net) is a website that publishes electronic
monographs (interactive identification and information retrieval
systems) on crustaceans at any taxonomic level. These monographs
are prepared using the DELTA system and include illustrated,
interactive keys to each group, as well as diagnoses, descriptions
and illustrations of each taxon in the group.
A series of international
workshops has been implemented to teach taxonomists
how to use DELTA to produce taxonomic information retrieval
systems for the website. The databases produced from these
workshops are presented on line, as they are finished, and
are accessible through the Australian Museum Online website.
Each database is held at the institution that produced it
and maintained by its author. In this way, interactive keys
to all of the world crustaceans can be developed over time.
The Crustacea.net project, as a whole, is effectively an
electronic monographic series to the world Crustacea. Each
participant who provides an interactive information and
retrieval system for the project becomes the author of a
monograph in the series. Any expert is welcome to participate.
As family, generic or species level groups are finished
they will be added to the website. The site is developed
and maintained by the Australian Museum, but has an independent
address (www.crustacea.net) because of its international
