Biologist – Definition, Types, Work Area




A biologist is a scientist who studies living organisms, including their structure, function, growth, evolution and distribution.

Biologists use a variety of techniques to study living organisms. They may collect samples from the field for laboratory analysis, or use microscopes and other scientific equipment to observe cells and tissues. Sometimes they may even conduct experiments on animals or plants to test hypotheses about how they work.

Types of Biologist

There are seven most common types of Biologists:

  • Forensic biologist
  • Microbiologist
  • Marine biologist
  • Wildlife biologist
  • Ecologist
  • Biological engineer
  • Biostatistician

Forensic Biologist

A forensic biologist is a scientist who uses biology to investigate crimes. Forensic biologists can use their knowledge of DNA and other biological evidence to solve crimes. They may also work with medical examiners to determine the cause of death in cases of homicide.


Microbiologists are scientists who study living organisms that are too small to be seen with the naked eye. These tiny creatures include bacteria, viruses, fungi, and protozoa. Microbiologists use a variety of techniques to study these organisms, including microscopes and DNA sequencing.

Marine Biologist

Marine biologists are scientists who study the plants and animals that live in salt water environments. These biologists may study microscopic organisms, such as plankton, or large mammals, such as whales. Marine biologists use their knowledge to help conserve these ecosystems and the species that live in them.

Wildlife Biologist

A wildlife biologist is someone who studies wild animals and their habitats. They may track the movements of animals, collect data on their populations, or study their behavior. Some wildlife biologists work in zoos or other captive animal facilities, while others may work in the field observing and researching animals in their natural habitat.


An ecologist is a scientist who studies ecosystems. Ecologists may study a particular ecosystem, such as a forest, or they may study many different types of ecosystems. They use their knowledge to help protect and conserve these ecosystems.

Biological Engineer

A biological engineer is someone who uses principles of biology and engineering to create solutions for problems in the life sciences. They work in a variety of fields, such as medical device design, food production, and pharmaceuticals.


A biostatistician is a scientist who uses statistics to study biological phenomena. Biostatisticians use their skills to design and analyze experiments, to develop statistical models of biological processes, and to analyze data from those experiments and models.

What Do Biologists Do

A biologist studies the living organisms in the natural world. They can specialize in a certain area, such as plants or animals, or they can study all living things. A biologist might study how a particular species adapts to its environment, how diseases spread through a population of animals, or the effects of pollution on plant life.

Most biologists spend their time conducting experiments and analyzing data. They may work in laboratories, greenhouses, offices, or field locations. Some biologists travel to remote areas to study plants and animals in their natural habitat.

What Skills Must a Biologist Have

Some of the most important skills for a biologist include critical thinking, problem-solving, observation, and communication. These skills are essential for conducting experiments, analyzing data, and drawing conclusions.

In addition to these core skills, biologists also need to be able to work well in teams and have strong writing skills. Being able to effectively communicate your findings is crucial in this field.

With the ever-growing demand for new scientific discoveries, those who have the skill set to become a biologist are in high demand. If you are interested in pursuing a career in biology, start honing your skills today!

Where Biologists Work

Most biologists work in research laboratories at colleges and universities, government agencies, or private companies. Many also work in field stations, zoos, botanical gardens, and aquariums. Some are employed as consultants to industry or environmental groups.

A few biologists teach in high schools or middle schools. Some conduct medical research or work as physicians or other health care providers. Biologists also work for wildlife management agencies and environmental organizations.

How to Become A Biologist

Becoming a biologist requires obtaining at least a bachelor’s degree in biology or related field. Some biologists may choose to pursue further education by obtaining a master’s degree or doctorate. After completing the necessary education, biologists typically find employment with government agencies, private companies, research institutions, etc. In some cases, experience in the field may be required before finding employment. Many biologists start their careers as research assistants or technicians.
