<P> Polymorphism refers to the occurrence of structurally and functionally more than two different types of individuals within the same organism . It is a characteristic feature of Cnidarians , particularly the polyp and medusa forms , or of zooids within colonial organisms like those in Hydrozoa . In Hydrozoans , colonial individuals arising from individuals zooids will take on separate tasks . For example , in Obelia there are feeding individuals , the gastrozooids ; the individuals capable of asexual reproduction only , the gonozooids , blastostyles and free - living or sexually reproducing individuals , the medusae . </P>
