Description:
Studies on the food and feeding habit of T. fuscatus var fuscatus from the mangrove swamps of the Bonny River, Niger Delta revealed that the species is a deposit feeder but fed more on algae and protozoa. The variation of food types with season were determined from the numerical and frequency of occurrence methods of food analysis. The algae were of Stephanodiscus, Cosanodiscus. Navicula and Nitzschia species, while the protozoa were Arecella arenaria, Pseudodileptus and Trinema species. Feeding actively occurred at low tides, this coincided with the presence of algae on the mud surface. No qualitative seasonal variation occurred as T. fuscatus var fuscatus fed basically on the primary diets at all seasons.
