Short summary
In the western tropical South Atlantic, coastward currents spread oceanic cnidarians over the continental shelf. While both coastal and oceanic communities co-occur in scenarios of higher runoff and weaker boundary current intensity, oceanic species dominate almost the entire shelf during the dry season characterized by stronger currents. Meanwhile, offshore, when the mixed-layer depth is shallower, the enhanced primary productivity supports larger populations of planktonic cnidarians.
