Expert Answer:

Polymorphism refers to the existence of two or more forms of individuals within the same animal species.
Polymorphism is common in nature; it is related to biodiversity, genetic variation and adaptation; it usually functions to retain variety of form in a population living in a varied environment. The most common example is sexual dimorphism, which occurs in many organisms. Other examples are mimetic forms of butterflies, and human hemoglobin and blood types.
Coelenterates include a large number of colonial species that contain more than one form of individuals which are called zooids. Coelenterates have two basic zooids, polyp and medusa.
