An on-line resource for the discovery, analysis, and dissemination of information on the evolution and ecology of the Leptostraca...

Click name for CV


As currently understood, the crustacean order Leptostraca comprises 10 genera and 39 species. These predominantly benthic organisms occur in marine environments worldwide, associated with habitats ranging from coral reefs to hydrothermal vents. Despite their ubiquity and a reasonably long history of descriptive work on the group, the order Leptostraca has been badly in need of taxonomic revision. As our work on the group and that of others (e.g., J. Moreira, J. Olesen) continues, our understanding of the group's diversity is improving.

Leptostracans belong to the phylum Arthropoda, the most diverse group of Metazoa (multicellular animals) on Earth.

The DELTA system is a set of programs used for the development of interactive taxonomic keys and natural language descriptions. The software serves as a powerful tool for managing anatomical (i.e., character) data and for constructing output directly from such data.

Research on the systematics of the Leptostraca is sponsored by the PEET program of the National Science Foundation.

This section will be revised to serve as an informative atlas of leptostracan anatomy, and to some extent that of Crustacea in general. A broader array of scanning electron micrographs and line drawings will be available. Some original line drawings are available via our Gallery link, and definitions of morphological terms can be accessed via our Glossary link.

New insights on the biology of leptostracans come primarily from first-hand study of the animals. The specimens studied are both from collections of museums worldwide and those collected from our own fieldwork. Interesting finds are coming to light every month, whether representing leptostracan species new to science or new information regarding the ecology and distribution of these crustaceans. For these discoveries, we also thank the many colleagues who send specimens us from around the globe.
