What Do Marine Biologists Do?

If it lives in the ocean, you can bet there's a marine biologist who's studying it. Marine biologists research the plants and animals that inhabit the oceans, studying their characteristics, behaviors, adaptations and habitats. They observe; they conduct experiments; they take samples and they make assessments, all in the hopes of understanding their place (and our place) in the world. Some may do this to help rescue a species from the brink of extinction, others may do it to manage food and resources for humans, and still others may do it to find cures for diseases or new advances in technology.

What's the Path to Becoming a Marine Biologist?

The path to becoming a marine biologists starts with a curiosity for the natural world. If you love the oceans, dive in and explore as much as you can. Research and get involved with oceanic rescue and volunteer organizations. Look for institutions of higher learning that offer degrees in marine biology or at least a related field like science or biology. During your undergraduate studies and after, find internships, fellowships and jobs that give you extra experience to add to a resume. If you want to pursue higher level work and specialize (on, say, the mating habits of dugongs), a Master of Science or a Ph.D. may be a wise step.
