What is a Marine Biologist?

A Marine Biologist studies, observes, protects or manages ocean organisms, which range from microscopic life forms to large whales.  

Marine Biologists spend a good amount of time researching a particular field of interest, whether in labs or in the sea itself – then specializing in it.

For example, a Marine Biologist can specialize in a particular species of jellyfish, the feeding behaviours of, the reproduction of or,  the development of new techniques to research jellyfish.

A Marine Biologist usually has a scuba diving certificate in addition to a university degree. Many with advanced degrees in marine biology pursue professorships in conjunction with their research pursuits.
