Marine Biologist

Marine biologists study ocean life to protect animals, plants, and habitats in the sea.

What they do

Marine biologists study creatures and plants that live in oceans and other waters. They research how animals behave, track ocean health, and work to protect endangered species and habitats from pollution and climate change.

Work environment

Their work happens in labs, on boats, and underwater while diving. Fieldwork can mean travel to coasts and remote areas, while research and writing happen at a desk.

How to become one

Earn a bachelor’s degree in marine biology or biology. Many roles, especially in research, require a master’s or PhD. Volunteering at aquariums or research centers is a great first step.

Skills you’ll need

  • Curiosity
  • Science and research
  • Patience
  • Swimming/diving
  • Writing

A day in the life

A marine biologist might collect water samples from a boat in the morning, record observations of dolphins, then return to the lab to study samples under a microscope and write up what they found.
