Marine biology
Marine biology is the study of any living plant or animal in the sea. Marine biologists 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.
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 expeditions aboard the HMS Beagle from 1831–1836 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
Marine animals include squids, corals, whales and fish. Marine plants include sea grasses and algae. The Census of Marine Life was a ten-year project of marine biology.
The lion-fish has a pattern of red, white, cream, or black stripes. This fish is an invasive species. This means that it should not be in as many waters as it is. Another animal is the clownfish is usually orange, or yellow, and black and white stripes. They are part of the Amphiprioninae family.
Marine biologist
Previous education is 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 zoology, invertebrate, ichthyology, and physiology. Others study physical traits like scales, scales, or eyes. Biologists also study animal behavior.
