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 .
Peter John Herring is an English marine biologist known for his work on the coloration, camouflage and bioluminescence of animals in the deep sea, and for the textbook The Biology of the Deep Ocean. Life
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
[10] [11] [12] Rather than host-associated microbes functioning independently, complex multi-assemblage microbiomes have major impact on the fitness and function of their hosts. Studying these complex interactions and biological outcomes is difficult, but to understand the origin and evolution of organisms and populations and the structure and ...
Marine conservationists rely on a combination of scientific principles derived from marine biology, Ecology, oceanography, and fisheries science, as well as on human factors, such as demand for marine resources, maritime law, economics, and policy, in order to determine how to best protect and conserve marine species and ecosystems.
Biological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system.Biological oceanography may also be referred to as ocean ecology, in which the root word of ecology is Oikos (oικoσ), meaning ‘house’ or ‘habitat’ in Greek.
Microorganisms make up about 70% of the marine biomass. [4] A microorganism, or microbe, is a microscopic organism too small to be recognised adequately with the naked eye. In practice, that includes organisms smaller than about 0.1 mm. [12]: 13
A marine ecoregion is an ecoregion, or ecological region, of the oceans and seas identified and defined based on biogeographic characteristics. Introduction [ edit ]
