Relationships

Sponges have different relationships with the marine and freshwater life around them. In some cases, other animals are protected by the sponge and live inside them, hiding from preditors. Some sponges attach themselves to corals and reside there until they die. This relationship though, is detrimental to the coral reef as the toxins and chemicals released injure and kill the coral. The sponges however, cannot determine where they land as they are at the mercy of the ocean currents.
