'''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]].

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 ==

== 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.

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''.

Don't forget that in the past sea creatures were as different from today as were land animals.<ref>Benton M.J. 1990. ''The reign of the reptiles''.

Previous education is a [[bachelor's degree]] in biology, followed by at least an [[MSc]] in marine biology.
