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.
Don't forget that in the past sea creatures were as different from today as were land animals.[1]
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.
Marine Biology Media
Marine biology studies species that live in marine habitats. Most of the Earth's surface is covered by ocean, which is the home to marine life. Oceans average nearly four kilometers in-depth and are fringed with coastlines that run for about 360,000 kilometres.

Coral reefs form complex marine ecosystems with tremendous biodiversity.

The open ocean is the area of deep sea beyond the continental shelves.
