Radio tracking technology has, for many years, been applied successfully to studies of vertebrates. particularly mammals and birds. Recent reductions in transmitter size have enabled these techniques to include invertebrates. However, perhaps because the radio tracking of invertebrates is especially problematic, relatively few studies have been carried out. In particular, there are relatively few radio tracking studies of decapod crustaceans, especially terrestrial species, Here we report the practical use of radio transmitters to track a tropical, amphibious fresh-water land crab, Eudaniela garmani, in the rainforests of the Caribbean island of Tobago. We include a method for gluing tags to the crabs' carapaces which allows individuals to be tracked for periods of up to 12 months. [References: 15]
