 The coastal and marine habitat flourished with their own species of vegetation as well, including many different types of sea grasses, kelp, corals, sponges, and roots(namely along the rocky coasts).Kasatochi Island was the home of many species, but most notable were the populations of diverse seabirds, avian predators and marine invertebrates.Ocean currents, productivity, and the habitable island geology created the ideal conditions for these select groups of fauna.
