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.
Most aspiring marine biologists complete a degree program in marine biology or a related science field, and seek out training or internship opportunities to prepare for the field. The term 'marine biologist' is often used indiscriminately for jobs that apply to the scientific observation and study of marine life.
