Animals can hide from predators in marsh vegetation, because the shallow brackish area physically excludes larger fish. 1 What effect does a decrease in pH have on urchins? How does the increase in nutrients affect the algae population? Sea urchin fisheries are unique in that they operate, at least in part, with overfishing as a goal in an effort to restore damaged ecosystems caused by urchin overabundance. In the top photo, Strongylocentrotus franciscanus is using the teeth on its five part jaw (see photo at left) to gnaw on the exoskeleton of a hermit crab (at arrow).
