How long does it take to become a marine biologist? Marine biologists must complete at least a bachelorâs degree, which takes about four years. Marine biologists who pursue masterâs degrees may take an additional two to three years to complete their education, and earning a PhD will take up to six years more.
If you want to become a marine biologist you will have to learn about science. Ask your teachers for projects to do with living creatures. Don't think that you only need to know biology. Marine creatures are made of chemicals and they are physical things, just like plastic toys and wooden chairs.
