An ecological study of the banded blennyParaclinus fasciatus (Steindachner, 1876) showed that the fish is tolerant of physical/chemical conditions in the shallow subtidal area of Apalachee Bay, Florida (USA). Population density ofP. fasciatus was unrelated to physical/chemical characteristics and seagrass biomass at field stations. A strong correlation was found between numbers ofP. fasciatus captured and abundance of unattached red algae (drift algae) at the field sites, although seasonality in population density was related to summer spawning. Spawning began at approximately 28°C. The life span of the clinid is probably little longer than 1 yr. Long-term variation in population size was also demonstrated.P. fasciatus was found to be a highly specialized carnivore which consumes only a few species of amphipods and shrimps; however, major seasonal variation in diet occurred. Variations in food habits were related to known patterns of prey abundance in Apalachee Bay. The most important prey species taken byP. fasciatus, includingCymadusa compta andHippolyte zostericola, are associates of red algae masses, further substantiating the close functional relationship of the clinid with its algal habitat which moves about the bay. The driftalgae habitat is probably an important source of shelter, food, and dispersal for the banded blenny. The eurytolerance ofP. fasciatus makes it particularly well adapted for life in an unusual, mobile habitat.
