Marine biology is a branch of biology. It is closely linked to oceanography, especially biological oceanography, and may be regarded as a sub-field of marine science. It also encompasses many ideas from ecology. Fisheries science and marine conservation can be considered partial offshoots of marine biology (as well as environmental studies).
General characteristics of a large marine ecosystem (Gulf of Alaska). 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 ...
Today, marine species range in size from the microscopic phytoplankton, which can be as small as 0.02–micrometres; to huge cetaceans like the blue whale, which can reach 33 m (108 ft) in length. [5] [6] Marine microorganisms have been variously estimated as constituting about 70% [7] or about 90% [8] [1] of the total marine biomass.
Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries. It is a branch of marine biology and botany.
Marine biology is a hybrid subject that combines aspects of organismal function, ecological interaction and the study of marine biodiversity. [1] The earliest studies of marine biology trace back to the Phoenicians and the Greeks who are known as the initial explorers of the oceans and their composition. [ 2 ]
Marine life is concerned with the plants, animals and other organisms that live in the ocean. 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 .
The Duke University Marine Laboratory (commonly referred to as the Duke Marine Lab) is a research facility and campus of Duke University on Piver's Island, [1] near Beaufort and the Outer Banks, North Carolina specializing in studying marine biology. It is part of the Nicholas School of the Environment's Division of Marine Science and ...
Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe) is any microscopic living organism or virus, which is invisibly small to the unaided human eye without magnification ...
