Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals.As an informal and colloquial grouping, they correspond to large members of the infraorder Cetacea, i.e. all cetaceans apart from dolphins and porpoises.

Examination of a 9 m (30 ft) giant squid, the second largest cephalopod, that washed ashore in Norway in 1954 In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range.
SEA LIFE Sydney Aquarium (formerly Sydney Aquarium) is a public aquarium in Sydney, Australia.Opened in 1988, it features a large variety of Australian aquatic life, displaying more than 700 species comprising more than 13,000 individual fish and other sea and water creatures from most of Australia's water habitats.
