Little do we know that these animals actually like to live in or near corals, which sometimes protect them from larger predators. They also get there food from corals other creatures that live in the coral. With the coral bleached and unalive, there is no source of food for the lobsters, crabs, and tuna, they have to find another place to eat and they most likely get eaten by biggers predators before they get a chance to find new
