What is a zoologist?

A zoologist is a scientist who studies animals. They may study an animal’s origins, genetics, diseases, behaviors, or more. With over 1.3 million identified animals in the world so far, it’s not surprising that zoology is a very broad field. 

A zoologist typically devotes their time to the study of 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 in captivity in zoos and aquariums. Zoologists observe animals, take meticulous notes, and conduct experimental studies in either controlled or natural surroundings. Some zoologists manage wildlife reserves where they keep a count of animal populations and study animal behavior.

Not all zoologists work in the field studying animals. Many work in labs where they study various biological aspects of animals. Others are professors at universities and colleges. They teach, conduct research, and write reports, scientific papers, and journal articles.

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.

Qualifications and eligibility

To become a zoologist, you must have at least a bachelor’s degree, typically in biology, zoology, or a related field. Graduate-level degrees, such as a master’s or a doctorate, are generally preferred and many times required for advanced research or teaching positions. Zoologists typically focus on a particular branch of zoology during their graduate studies. 

Along with science courses, such as biology, anatomy and physiology, chemistry, and physics, students are required to take statistics, communications, and computer technology. Additional courses in animal science, veterinary science, animal behavior, animal husbandry, and ecology can be very beneficial. 

A zoologist should have excellent communication skills, both verbal and written, as they often present research findings and write research papers and reports. They also need keen observation skills to identify animal behavior, appearance, and the effects of the environment on the animals they study. Critical thinking is important as zoologists need to develop theories and draw conclusions from experiments, research, and scientific observations. They often need to find solutions to issues affecting animals and need good problem-solving skills to do so. Computer literacy and the ability to work with highly specialized scientific equipment are also important skills zoologists need.

Work environment

Zoologists work in a variety of environments. They might 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. They often endure a wide range of 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 taking care of animals. Others are employed at museums where they set up and maintain exhibits and educate the public on different species of animals. Other environments that zoologists work in include marine parks, state or federal governmental agencies, environmental conservation groups, and consulting companies.

Typical work hours

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 remote locations. The work and the hours can be unpredictable. 

Professors tend to work flexible hours as classroom schedules change each semester. They spend some hours of their day in the lab conducting research. 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. 

Types of zoologists

There are many different types of zoologists as the animal kingdom is very large. While some study only a species or subspecies, others might study a wider, 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. 


Primatology is the study of primates, including gorillas, orangutans, chimpanzees, and lemurs. Primatology incorporates field study, laboratory study, 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. Ornithologists study bird behavior, flight, migration patterns, habitats, physiology, and much more. There are over 18,000 different species of birds, allowing ornithologists to generalize or specialize in a specific bird species.


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, which include 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 from arachnid populations, evolution, diversity, venom, webs, and predatory tactics. 


Acarology is the study of mites and ticks, which are arachnids, so acarology is a sub-branch of arachnology. 


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


Malacology is the study of mollusks, such as snails and clams.
