This document is a pretrip instruction manual that can be used by secondary school and college teachers who are planning trips to visit the tropical habitats in South Florida. The material is divided into two parts: (1) several fact sheets on the various habitats in South Florida; and (2) a number of species lists for various areas. Factsheets on the classification of marine environments, the zones of the seashore, estuaries, mangroves, seagrass meadows, salt marshes, and coral reefs are included. The species lists included algae, higher plants, sponges, worms, mollusks, bryozoans, arthropods, echinoderms, vertebrates, insects, and other invertebrates. The scientific name, common name, and a brief description are supplied for all species. Activities on the behavior and social life of fish, a dichotomous key for seashells, and a section that lists useful references for Florida field trips are included. (KR)
