Ayana Elizabeth Johnson (born 1980 or 1981 [5]) is a marine biologist, policy expert, and conservation strategist. She is the co-founder of Urban Ocean Lab, a think tank for ocean-climate policy in coastal cities, [2] [6] and the Roux Distinguished Scholar at Bowdoin College. [7]
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 .
An average of 2,332 new species per year are being described. Marine life is studied scientifically in both marine biology and in biological oceanography. 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 ...
Charles Atwood Kofoid (11 October 1865 – 30 May 1947) was an American zoologist known for his collection and classification of many new species of marine protozoans which established marine biology on a systematic basis. Kofoid also wrote a volume on the biological stations of Europe. [1]
[1] 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 ...
Marine invertebrates are the invertebrates that live in marine habitats. Invertebrate is a blanket term that includes all animals apart from the vertebrate members of the chordate phylum. Invertebrates lack a vertebral column , and some have evolved a shell or a hard exoskeleton .
Marine waters cover more than 70% of the surface of the Earth and account for more than 97% of Earth's water supply [1] [2] and 90% of habitable space on Earth. [3] Seawater has an average salinity of 35 parts per thousand of water. Actual salinity varies among different marine ecosystems. [4]
