Scuba Schools International (SSI) has introduced a new Nudibranch Ecology Specialty to enhance its environmental programs. This course includes seven lessons that explore nudibranchs’ habitats, feeding habits, movement, and their role in marine ecosystems. The addition follows the earlier launch of the Marine Invertebrate Ecology Specialty and increases SSI’s environmental specialties to nine. This is a great opportunity for divers to learn more about these fascinating creatures and their importance in the ocean.
