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.
General characteristics of a large marine ecosystem (Gulf of Alaska) Killer whales (orcas) are highly visible marine apex predators that hunt many large species. But most biological activity in the ocean takes place with microscopic marine organisms that cannot be seen individually with the naked eye, such as marine bacteria and phytoplankton.
The earliest animals were marine invertebrates, that is, vertebrates came later. Animals are multicellular eukaryotes, [note 1] and are distinguished from plants, algae, and fungi by lacking cell walls. [1]
Saltwater fish, also called marine fish or sea fish, are fish that live in seawater.Saltwater fish can swim and live alone or in a large group called a school. [1]Saltwater fish are very commonly kept in aquariums for entertainment.
A school of large pelagic predator fish (bluefin trevally) sizing up a school of small pelagic prey fish (). Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that live on or near the bottom, and reef fish that are associated with coral reefs.

Bunaken National Park is a marine park in the north of Sulawesi Island, Indonesia.The park is located near the centre of the Coral Triangle, providing habitat to 390 species of coral [2] as well as many fish, mollusks, reptiles and marine mammal species.
Seafood is any form of sea life regarded as food by humans, prominently including fish and shellfish.Shellfish include various species of molluscs (e.g., bivalve molluscs such as clams, oysters, and mussels, and cephalopods such as octopus and squid), crustaceans (e.g. shrimp, crabs, and lobster), and echinoderms (e.g. sea cucumbers and sea urchins).
