However, they did see an increased effect of predation on the open site rather than the closed site which was seen in our experiment as well. This shows that, while substrate is important, the type of enclosure we used also had an effect on the accumulated biomass over time. The influence of predation has a definite effect on the distribution of meiofauna in soft-sediment communities Callinectes sapidus, commonly called the blue crab, is a benthic opportunistic predator found along the Atlantic coast.
