Trailing decreases the light and visibility within the water, which may interfere with the circulation along with foraging capacities of certain types. The debris surrounding seawalls has a tendency to have much less favorable physical properties (Higher calcification levels, less architectural organization of crystalline framework, low silicon web content, and much less macroscale roughness) when compared to all-natural coastlines, which can provide concerns for species that stay on the seafloor.
