This chapter presents information on the influence of major physicochemical factors including depth, temperature, salinity, turbidity, sediment texture, dissolved oxygen, pH, nutrients, organic matter, redox potential index, and contaminates on the marine benthos. Benthic assemblages encompassing macro and meiobenthos in all the regions including intertidal (soft and rocky), estuarine, coastal and deep seas occurring in different substrata are tied to the interplay of the environmental parameters. Salinity, dissolved oxygen concentration, temperature, depth, latitudinal variations, level of nutrients, and turbidity directly and indirectly influence the distribution, abundance, and larval survival of benthos as well as food availability among benthic organisms. Sediment composition is also interconnected to the complex relationship of other parameters with benthos besides contaminants. The establishment of a database on the environmental parameters in the benthic environment and their role in the distribution of benthic organisms will help monitor the benthic environment and its health.
