Outdoors or in a laboratory

The US Bureau of Labor Statistics says zoologists and wildlife biologists work in offices and laboratories and may spend time outdoors, studying animals in their natural habitats. Microbiologists work primarily in laboratories and offices, and most biochemists and biophysicists work in laboratories.

Named in Greek for what they study

Many titles come from Ancient Greek. An ornithologist is named for órnis, bird; a dendrologist for dendron, tree; a cetologist for kētos, whale; a myrmecologist for myrmex, ant; and a limnologist for límnē, lake.

Questions and answers

What are the different types of biologists?

Some are named for the living things they study, such as botanists (plants), entomologists (insects) and virologists (viruses). Others are named for a scale or a question: cell biologists, geneticists, ecologists and evolutionary biologists.

How do I know what type of biologist I should be?

Ask where you want to spend your days. The Bureau of Labor Statistics says fieldwork can be physically demanding, in all types of weather, and may mean travel to remote locations for long periods. If that appeals, start with the animal and ecosystem groups.

What degree does a biologist need?

For zoologists and wildlife biologists, the Bureau of Labor Statistics says a bachelor’s degree is typical for entry-level positions, a master’s degree may be needed for higher level jobs, and a Ph.D. is typically needed to lead research projects.

What is a biologist who studies the ocean called?

A marine biologist studies life in the sea. Narrower titles name what is studied: an ichthyologist studies fish, a teuthologist studies octopuses and other cephalopods, and a planktologist studies plankton.

All 76 kinds of biologist

Sea and fresh water 11

  • Biological oceanographer Studies how organisms affect and are affected by the ocean’s physics and chemistry.
