A total of 71,931 coastal pools were mapped and measured, and amphibian occupants were identified along 48 km of shoreline at Isle Royale National Park, where coastal rock pool habitats were abundant. It mostly eats small fish, crabs and mussels. The low tide zone is mixed with organisms that can be found in both the intertidal and sub-tidal habitats and is characterized by the large fleshy brown algae. They can be found as far north as Alaska and as far south as Mexico. These guys can be found both in the water and on the shore!
