Types of Seas and their Biological Characteristics

Sudheer Nadella

World Ocean or seas are containing the marginal seas, areas of water lands, various gulfs resources, bights, bays, and straits etc. Marines may be examined the margins between the ocean and land or between the oceans in which are case they may be treated as marginal parts of either. There is no unique eventual authority on the matter. However, some categories are such as mammals, birds, spiders, and oligochaetes, are more diverse on the sea land. A few land animals are included as e.g., amphibians, are fully absent from the sea, and all the birds reproduce on land, even if some such as penguins, petrels, albatrosses, etc. feed exclusively in or on the sea on coastal animals. Among insects, only hylobatid bugs run on the ocean exterior and larvae of some chironomid gnats live in the coastal waters of coral reefs. Faunal biodiversity within non-identical taxonomic categories (phyla, classes) significantly varies.
