What is Marine biology?
'''Marine biology''' is the [[Research|study]] of any [[life|living]] plant or [[animal]] in the [[sea]]. [[Ocean|Marine]] [[biologist]]s study it. Like other scientists, marine biologists must know a lot about the creatures they are studying. They also must understand how the sea works. The study of how the sea works is [[oceanography]]. Marine animals include [[squid]]s, [[coral]]s, [[whale]]s and [[fish]]. Marine plants include [[sea grass]]es and [[algae]]. The [[Census of Marine Life]] was a ten-year project of marine biology. Like land animals, marine animals have been evolving for hundreds of millions of years, <ref>Benton M.J. 1990. ''The reign of the reptiles''. ISBN 0-517-02557-4</ref> thus [[trilobite]]<nowiki/>s and [[ammonite]]<nowiki/>s are no more, but now there are whales. Biologists also study [[animal behavior]]. A marine biologist needs a [[bachelor's degree]] in biology, followed by at least an [[MSc]] in marine biology. The ocean is large and marine biologists work in many subfields like [[invertebrate]] zoology, [[ichthyology]], and physiology. Others study physical traits like scales, eyes, or shells. == History == During the [[Age of Discovery]] many ships sailed far from home. Captain [[James Cook]] went twice around the world and discovered new places. Another person who helped is [[Charles Darwin]], known for the Theory of [[Evolution]]. He worked in marine biology. His [[expedition]]s aboard the HMS Beagle from 1831{{ndash}}1836 collected marine organisms. Several other people also made important voyages. [[Alfred Russel Wallace]] spent much of his younger life travelling the world and recording the plants and animals he saw. == References == {{reflist}} == Other websites == {{commonscat}} * [https://www.environmentalscience.org/career/marine-biologist What is a marine biologist?] -Careers * [https://utmsi.utexas.edu/academics/undergraduate/what-is-marine-biology What is marine biology?] {{Webarchive|url=https://web.archive.org/web/20190523164201/https://utmsi.utexas.edu/acad
