Zoologist Career Guide

What is a zoologist?

A zoologist is a scientist who studies animals, an animal’s origins, genetics, diseases, behaviors, and more. With over 1.3 million identified animals in the world so far, it’s unsurprising that zoology is a very broad field. 

A zoologist typically devotes their time to studying one specific species or group of species, although some do more general work. They work in the field studying animals in their natural environment or captivity in zoos and aquariums. zoologists observe animals, take meticulous notes, and conduct experimental studies in controlled or natural surroundings. Some zoologists manage wildlife reserves where they keep count of animal populations and study animal behavior.

Duties and responsibilities

On any given day, a zoologist may be designing or conducting research, studying animal behaviors and characteristics, collecting and analyzing biological data and specimens, writing papers, reports, or journal articles, giving lectures, or educating the public on animal welfare and wildlife conservation.

Work environment

Zoologists work in a variety of environments. They can be professors teaching at universities and colleges where they are either in the classroom or conducting research in a lab setting. Aside from giving lectures and presenting research, they write papers and journals for publication. Other zoologists work exclusively in lab-based environments performing experiments and conducting research. They spend some of their time writing reports and papers. Many zoologists spend at least part of their time outdoors, studying animals on wildlife reserves or in their natural habitats. Often they endure various environmental and weather conditions while in the field. They may also only have limited comforts. Field zoologists can sometimes work in remote areas and be away from friends and family for days, weeks, or months at a time.

Some zoologists work at zoos or aquariums, observing and caring for animals. Others are employed at museums where they set up and maintain exhibits and educate the public on different species of animals. Other environments zoologists work in include marine parks, state or federal governmental agencies, environmental conservation groups, and consulting companies.

Typical work hours

The work and the hours can be unpredictable. Zoologists working in the field often work long hours, which may include nights and weekends. They can spend days, weeks, or even months in the field, which may be in remote locations. 

Professors tend to have more flexible hours since classroom schedules change each semester. They spend some hours of their day in the lab conducting research, and they typically don’t work weekends but can work nights in the classroom. 

Zoologists in labs generally work traditional 40-hour weeks during normal business hours. Consultants for private companies also work 40-hour weeks from Monday through Friday.

How to become a zoologist

Step 1: High school preparation

If you’re still in high school, this is the time to concentrate on the classes that will help you get into college and lay the foundation for much of your college work. Focus on biology and chemistry courses. Take all you can. Volunteer or find a part-time job at a local zoo, aquarium, or animal sanctuary. Get all the experience you can.

Step 2: Get a bachelor’s degree

Most colleges and universities offer a bachelor’s degree in biology, and many also have a zoology degree program. Most programs include core courses in general biology, chemistry, physics, and mathematics. Some university programs have specialized courses you can take, including marine biology, wildlife ecology, mammalogy, herpetology, ornithology, and animal physiology.

Step 3: Gain experience

Beyond your education, you will need hands-on experience even for an entry-level zoologist position. While working on your bachelor’s degree, you can find opportunities for volunteer work, co-op programs, and internships. Some of this work may count for college credit, but they all provide valuable experience, whether that includes fieldwork, research, writing papers, or more. Experience can also be beneficial in gaining acceptance to a graduate degree program. Some of the top internships for undergraduates students in 2022 include:

Step 4: Get a master’s degree

A master’s degree program is where you might specialize in a particular branch of zoology and generally assist research professors in their specialties as teacher’s assistants or research assistants. Master’s programs may consist of a thesis or non-thesis option.

Step 5: Get a doctoral degree

If you are interested in teaching at the university level or want to conduct your own independent research, you will likely need a doctorate in zoology. Zoologists focus on a specific sub-discipline of zoology while working on their doctorate. It is critical to apply to doctorate programs at universities where at least one professor specializes in your desired area of study.

Step 6: Participate in ongoing learning and professional development

Zoology is a constantly evolving field. Stay current with the latest research and trends by attending scientific conferences, participating in webinars, or joining professional organizations, such as the American Society of Mammalogists or the Animal Behavior Society.

Types of zoologists

There are many different types of zoologists because the animal kingdom is enormous. While some study only a species or subspecies, others might study a broader, more generalized group, such as mammals. Some common branches of zoology include:


Ethology is the study of animal behavior, typically in the animal’s natural habitat. These scientists observe animals and study their findings to learn about the animals’ social interactions, communication, and other aspects of their lives. They also conduct experiments to test hypotheses regarding animal behavior.


Primatology is the study of primates, including gorillas, orangutans, chimpanzees, and lemurs. It incorporates field, laboratory, and semi-free range study (a natural habitat replicated in a captive setting).

Wildlife biologists

Wildlife biologists observe and study animal behavior to maintain and conserve wildlife populations. They track things like disease and nutrition and monitor endangered populations. Wildlife biologists may specialize in entomology, ornithology, herpetology, marine biology, or other branches of wildlife biology.


Paleozoologists study extinct and surviving animal remains, including bone, horn, hair, and soft tissues. They may work alongside paleontologists at archaeological sites. 


Mammalogy is the study of mammals. This may include the natural history, taxonomy, systematics, anatomy, physiology, and behavior of mammals. With over 4,000 species of living mammals and many extinct species, mammalogists have a wide range of animals to study and typically specialize in one species. They may work in the field, zoos, natural history museums, or in research labs at colleges, universities, or other educational institutions.


Herpetology is the study of reptiles and amphibians, such as snakes, frogs, turtles, salamanders, crocodiles, and iguanas. Herpetologists study these animals in their natural environments, assess any possible threats from disease and pollution, and study their behaviors, physiologies, development, and genetics. They also work for museums and zoos. 


Ornithology is the study of birds. There are over 18,000 species of birds, allowing ornithologists to generalize or specialize in a specific bird species. They study bird behavior, flight, migration patterns, habitats, and physiology.


Entomology is the study of insects. This is by far the broadest branch of zoology as insects make up approximately 80% of the animal population, and well over 1 million species have been identified. Most entomologists focus on a specific type of insect, such as bees, beetles, or butterflies. Some entomologists look at ways to control insects. 


Arachnology is the study of arachnids, including spiders, scorpions, and Opiliones (or daddy longlegs). This is another vast group of animals as there are over 45,000 species of spiders alone. Arachnologists study everything, such as arachnid populations, evolution, diversity, venom, webs, and predatory tactics. 


Cetology is the study of sea mammals, including whales, dolphins, and porpoises. They study the behaviors, habitats, and interactions between these creatures. Cetologists in the field often spend hours or days in boats observing these animals in their natural habitat. They often use tagging and tracking systems to monitor the movements and migrations of sea mammals. 


Ichthyology is the study of fish, including their behavior, development, and reproduction. There are about 34,800 species of fish to study, and most ichthyologists study only one species. Some ichthyologists work in museums, while others work in the field, often conducting underwater research.
