Crab and sea anemone show mutualism in which hermit crab gets protection and sea anemone moves from place to place.
Sucker fish (Echeneis) and shark show commensalism. Sucker fish has a sucker or holdfast, which is modified dorsal fin. It attaches to the underside of shark and therefore remains protected. The fish obtains its food from small pieces of left over when shark is feeding on its prey.
Cuscuta is an angiosperm, which is total stem parasite on Cissus and other plants.
Tiger is natural predator of deer and kills deer to feed on it.
