It is typically found on coastal seabeds around northwestern Europe. - The physalia also known as the man-of-war, belongs to the phylum coelenterata, is a marine hydrozoan found in the Atlantic Ocean and the Indian Ocean . - Pinctada is a genus of saltwater Oysters, marine bivalve mollusca in the family pteridae, belongs to phylum Mollusca. There pearl oysters have a strong inner shell layer composed of nacre, also known as "mother of pearl". - Planarian, (class turbellaria), any of a group of widely distributed mostly free living flatworms of the class turbellaria (phylum platyhelminthes).

In which of the following class polymorphism is very distinct ?
1 Class-Euccstoda
2 Class-Hydrozoa
3 Class-Crinoidea
4 Class-Gastropoda
Explanation:
B The phenomenon of polymorphism is mainly seen in the class-hydrozoa. Polymorphism : Polymorphism is the ability of an object to take an different forms. Class-hydrozoa : The Hydrozoa is a class of Cnidarians they are characterized by having a life-cycle involving sexual and asexual reproduction. Example : Fresh Water Jelly, Fresh water polyps (Hydra) obelia, Portuguese man of war (Physalia), Pinkhearted Hydroids (tubularia).
