Marine biologists study fish and other wildlife that inhabit the oceans.
Zoologists and wildlife biologists typically need a bachelor’s degree for entry-level positions; a master’s degree is often needed for higher level investigative or scientific work. A Ph.D. is necessary to lead independent research and for most university research positions.
Employment of zoologists and wildlife biologists is projected to grow 4 percent from 2019 to 2029, about as fast as the average for all occupations. Zoologists and wildlife biologists will be needed to study human and wildlife interactions as the human population grows and development impacts wildlife and their natural habitats. However, because most funding comes from governmental agencies, demand for zoologists and wildlife biologists will be limited by budgetary constraints.
Zoologists and wildlife biologists work in offices, laboratories, or outdoors. Depending on their job, they may spend considerable time in the field gathering data and studying animals in their natural habitats.
