Zoologists and Wildlife Biologists

Summary

What Zoologists and Wildlife Biologists Do About this section

Marine biologists study fish and other wildlife that inhabit the oceans.

Zoologists and wildlife biologists study animals and other wildlife and how they interact with their ecosystems. They study the physical characteristics of animals, animal behaviors, and the impacts humans have on wildlife and natural habitats.

Duties

Zoologists and wildlife biologists typically do the following:

• Develop and conduct experimental studies with animals in controlled or natural surroundings
• Collect biological data and specimens for analysis
• Study the characteristics of animals, such as their interactions with other species, reproduction, population dynamics, diseases, and movement patterns
• Analyze the influence that human activity has on wildlife and their natural habitats
• Research, initiate, and maintain ways of improving breeding programs that support healthy game animals, endangered species, or other wild populations of land or aquatic life
• Estimate, monitor, and manage wildlife populations and invasive plants and animals
• Develop and implement programs to reduce risk to human activities from wildlife and invasive species, such as keeping wildlife from impacting airport operations or livestock and crop production
• Write research papers, reports, and scholarly articles that explain their findings
• Give presentations on research findings to academics and the general public
• Develop conservation plans and make recommendations on wildlife conservation and management issues to policymakers and the general public

Zoologists and wildlife biologists perform a variety of scientific tests and experiments. For example, they take blood samples from animals to assess their nutrition levels, check animals for disease and parasites, and tag animals in order to track them. Although the roles and abilities of zoologists and wildlife biologists often overlap, zoologists typically conduct scientific investigations and basic research on particular types of animals, such as birds or amphibians, whereas wildlife biologists are more likely to study specific ecosystems or animal populations, such as a particular at-risk species. Wildlife biologists also do applied work, such as the conservation and management of wildlife populations.

Zoologists and wildlife biologists use geographic information systems (GIS), modeling software, and other computer programs to estimate wildlife populations and track the movements of animals. They also use these computer programs to forecast the spread of invasive species or diseases, project changes in the availability of habitat, and assess other potential threats to wildlife.

Zoologists and wildlife biologists conduct research for a variety of purposes. For example, many zoologists and wildlife biologists work to increase our knowledge and understanding of wildlife species. Traditionally, many wildlife biologists researched ways to encourage abundant game animal populations to support recreational hunting and tourism. Today, many also work with public officials in conservation efforts that protect species from threats and help animal populations return to and remain at sustainable levels.

Most zoologists and wildlife biologists work on research teams with other scientists and technicians. For example, zoologists and wildlife biologists may work with environmental scientists and hydrologists to monitor water pollution and its effects on fish populations.

Zoologists generally specialize first in either vertebrates or invertebrates and then in specific species. Following are some examples of specialization by species:

• Cetologists study marine mammals, such as whales and dolphins.
• Entomologists study insects, such as beetles and butterflies.
• Herpetologists study reptiles and amphibians, such as snakes and frogs.
• Ichthyologists study wild fish, such as sharks and lungfish.
• Malacologists study mollusks, such as snails and clams.
• Mammalogists study mammals, such as monkeys and bears.
• Ornithologists study birds, such as hawks and penguins.
• Teuthologists study cephalopods, such as octopuses and cuttlefish.

Other zoologists and wildlife biologists are identified by the aspects of zoology and wildlife biology they study, such as evolution and animal behavior. Following are some examples:

• Anatomy is the study of structure of organisms and their parts.
• Embryology is the study of the development of embryos and fetuses.
• Ethology, sometimes called behavioral ecology, is the study of animal behaviors as natural or adaptive traits.
• Histology, or microscopic anatomy, is the study of cells and tissues in plants and animals.
• Physiology is the study of the normal function of living systems.
• Soil zoology is the study of animals which live fully or partially in the soil.
• Teratology is the study of abnormal physiological development.
• Zoography is the study of descriptive zoology, and describes plants and animals.

Many people with a zoology and wildlife biology background become high school teachers or college or university professors. For more information, see the profiles on high school teachers and postsecondary teachers.

Work Environment About this section

Fieldwork can require zoologists and wildlife biologists to travel to remote locations anywhere in the world.

Zoologists and wildlife biologists held about 17,100 jobs in 2021. The largest employers of zoologists and wildlife biologists were as follows:

Zoologists and wildlife biologists work in offices, laboratories, and outdoors. Depending on their job and interests, they may spend considerable time in the field gathering data and studying animals in their natural habitats. Other zoologists and wildlife biologists may spend very little time in the field.

Fieldwork can require zoologists and wildlife biologists to travel to remote locations anywhere in the world. For example, cetologists studying whale populations may spend months at sea on a research ship. Other zoologists and wildlife biologists may spend significant amounts of time in deserts or remote mountainous and woodland regions. The ability to travel and study nature firsthand is often viewed as a benefit of working in these occupations, but few modern amenities may be available to those who travel in remote areas.

Fieldwork can be physically demanding, and zoologists and wildlife biologists work in both warm and cold climates and in all types of weather. For example, ornithologists who study penguins in Antarctica may need to spend significant amounts of time in cold weather and on ships, which may cause seasickness. In all environments, working as a zoologist or wildlife biologist can be emotionally demanding because interpersonal contact may be limited.

Injuries and Illnesses

Some zoologists and wildlife biologists handle wild animals or spend significant amounts of time outdoors in difficult terrain or in inclement weather. To avoid injury, they should use caution when handling wildlife or working in remote areas.

Work Schedules

Most zoologists and wildlife biologists work full time. They may work long or irregular hours, especially when doing fieldwork. Zoologists and wildlife biologists who work with nocturnal animals may need to work at night at least some of the time.

How to Become a Zoologist or Wildlife Biologist About this section

Zoologists and wildlife biologists study specimens collected in the field.

Zoologists and wildlife biologists typically need a bachelor’s degree for entry-level positions and may need a master’s degree for higher level jobs. A Ph.D. is typically needed for leading independent research and for university research positions.

Education

Zoologists and wildlife biologists typically need a bachelor’s degree to enter the occupation. Students may pursue a degree in zoology, wildlife biology, or a related field, such as natural resources. Some students major in biology and take coursework in zoology and wildlife biology.

Zoologists and wildlife biologists typically need at least a master’s degree for higher level investigative or scientific work. A Ph.D. is necessary for most independent research and university research positions.

Coursework in life and physical sciences often includes academic, laboratory, and field work. In addition, students may need to take mathematics and statistics to learn data analysis.

Important Qualities

Communication skills. Zoologists and wildlife biologists write scientific papers and give talks to the public, policymakers, and academics.

Critical-thinking skills. Zoologists and wildlife biologists need sound reasoning and judgment to draw conclusions from experimental results and scientific observations.

Emotional stamina and stability. Zoologists and wildlife biologists may need to endure long periods with little human contact. As with other occupations that deal with animals, emotional stability is important in working with injured or sick animals.

Interpersonal skills. Zoologists and wildlife biologists typically work on teams. They must be able to work effectively with others to achieve their goals or to negotiate conflicting goals.

Observation skills. Zoologists and wildlife biologists must be able to notice slight changes in an animal’s behavior or appearance.

Outdoor skills. Zoologists and wildlife biologists may need to chop firewood, swim in cold water, navigate rough terrain in poor weather, carry heavy packs or equipment long distances, or perform other activities associated with life in remote areas.

Problem-solving skills. Zoologists and wildlife biologists try to find the best possible solutions to threats that affect wildlife, such as disease and habitat loss.

Other Experience

Some zoologists and wildlife biologists may need to have well-rounded outdoor skills. They may need to be able to drive a tractor, boat, or ATV, use a generator, or provide for themselves in remote locations.

Many zoology and wildlife biology students gain practical experience through internships, volunteer work, or some other type of employment during college or soon after graduation.

Advancement

Zoologists and wildlife biologists typically receive greater responsibility and independence in their work as they gain experience. More education also can lead to greater responsibility. Zoologists and wildlife biologists with a Ph.D. usually lead independent research and control the direction and content of projects. In addition, they may be responsible for finding much of their own funding.

Job Outlook About this section

Employment of zoologists and wildlife biologists is projected to show little or no change from 2021 to 2031.

Despite limited employment growth, about 1,500 openings for zoologists and wildlife biologists are projected each year, on average, over the decade. Most of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.

Employment

Demand for zoologists and wildlife biologists may be limited by budgetary constraints, as jobs and funding for these workers often come from state, federal, and local governments. However, some  zoologists and wildlife biologists are expected to be needed to help combat the loss of biodiversity caused by human activities, as well as to research climate-driven ecosystem changes. These workers also may be needed to develop and implement conservation plans to reduce threats to animals and protect natural resources.
