Florida's Indian River Lagoon (IRL) is recognized as possibly the most biologically diverse estuarine system in the continental US. The Smithsonian Marine Station at Fort Pierce manages the IRL Species Inventory Project, which includes an online database of taxonomic, ecological, and life history information of species in the estuary. Researchers, educators, and resource managers are encouraged to make use of the IRL Species Inventory Project, which will be expanded as research continues. The database includes a search engine with helpful tips, species reports; alphabetized species lists, detailed descriptions of IRL habitats, and more. A photo gallery has been recently added, featuring the work of local photographers.
