Charles Darwin aged 51
Charles Darwin is a famous biologist.

A biologist is a scientist who studies biology. Biologists study living organisms. There are many different kinds of biologists. Some of these include:

Specialists

EPA GULF BREEZE LABORATORY, FISHERY BIOLOGIST CONDUCTS STUDIES OF SHRIMP AND CRAB LARVAE
Biologist conducting research.

Most biological scientists specialize in the study of a certain type of organism or in a specific activity, although recent advances have blurred some traditional classifications.

  • Zoologists and wildlife biologists study animals and wildlife—their origin, behavior, diseases, and life processes. Some experiment with live animals in controlled or natural surroundings, while others dissect dead animals to study their structure. Zoologists and wildlife biologists also may collect and analyze biological data to determine the environmental effects of current and potential uses of land and water areas. Zoologists usually are identified by the animal group they study. For example, ornithologists study birds, mammalogists study mammals, herpetologists study reptiles and amphibians, ichthyologists study fish, cnidariologists study jellyfishes and entomologists study insects.
  • Botanists study plants and their environments. Some study all aspects of plant life, including algae, lichens, mosses, ferns, conifers, and flowering plants; others specialize in areas such as identification and classification of plants, the structure and function of plant parts, the biochemistry of plant processes, the causes and cures of plant diseases, the interaction of plants with other organisms and the environment, the geological record of plants and their evolution. Mycologists study fungi, such as yeasts, mold and mushrooms, which are a separate kingdom from plants.
  • Aquatic biologists study micro-organisms, plants, and animals living in water. Marine biologists study salt water organisms, and limnologists study fresh water organisms. Much of the work of marine biology centers on molecular biology, the study of the biochemical processes that take place inside living cells. Marine biology is a branch of oceanography, which is the study of the biological, chemical, geological, and physical characteristics of oceans and the ocean floor. (See the Handbook statements on environmental scientists and hydrologists and on geoscientists.)
  • Ecologists investigate the relationships among organisms and between organisms and their environments, examining the effects of population size, pollutants, rainfall, temperature, and altitude. Using knowledge of various scientific disciplines, ecologists may collect, study, and report data on the quality of air, food, soil, and water.
