Zoologists study the structure, physiology, development and classification of animals. They also study the habitats and ecology of animals. Zoology as a branch of life sciences involves work with animals, either in natural surroundings or in captivity. Because of the vastness of the animal kingdom, some zoologists specialize in one of the various branches that fall under this category. They may also choose to focus on whole organisms or parts of an organism. Zoologists conduct analytical and experimental research. They work in the field observing animals and their habitats and collect samples for analysis. They may have to work long irregular hours in remote areas and harsh climatic conditions. The samples collected by field work are examined in laboratories using specialized techniques. High technology software and computer simulations and models are used to analyze the laboratory results. Zoologists help in improving livestock, and facilitate development of new drugs for veterinary usage. Their work is invaluable in the field of animal welfare and conservation of endangered species and habitats. They are employed by the government to aid in developing policies and laws related to animals, both wild and domestic. They also serve in teaching positions in universities and undertake research. Read on to learn about the life and works of various famous zoologists from all over the world.
