What is Zoology

Zoology is a branch of biology that is dedicated to the study of animals. The word zoology comes from the Greek ζωον (zoon), which means ‘animal’, and –λογία (-logía), which translates ‘study’ or ‘science’.

The main objective of zoology is the examination of the morphological and anatomical description of the various animal species.: their reproduction, development, behavior and distribution.

In zoology there are different branches that are in charge of the various aspects of animals, among which we can mention:

  • zoographywhich is dedicated to the description of animals.
  • animal anatomywhich is responsible for observing the organisms of animals.
  • animal physiologywhich analyzes the chemical and physical functioning of the organism of animals.
  • zoogeographywhich looks at the relationships between animals, their environment, and their geographic distribution.
  • paleozoologywho studies fossil animals.

Likewise, there are other branches of zoology dedicated to working with specific species of animals.

Zoologists are the specialists in charge of the biological taxonomy of all species of animals, both living and dead. Some zoologists work as museologists, and are in charge of the maintenance and description of zoological collections.

The first zoologist in history was Aristotle, who, with the creation of the taxonomy, detailed numerous species and elaborated an outline of the animal classification, although many of his conclusions lacked scientific rigor and were rejected during the Renaissance, a time in which zoological investigations began to take on a character scientific. Added to this, the discovery of the microscope in those years by Anton van Leeuwenhoek allowed the study of the tissues of animals and previously unknown beings.

Likewise, the British naturalist Charles Darwin made very important contributions to zoology with the Theory of the evolution of species, which indicates that each individual of a species develops a quality that allows it to adapt to its habitat, survive and reproduce, and inherit this adaptive virtue to its descendants; on the other hand, the worst adapted individuals do not survive and, therefore, do not leave offspring, causing the extinction of their species.

The term of zoology It was fixed in the 17th century by the naturalist Johann Sperling, who established it in one of his works physical zoologypublished in 1661, after his death.

applied zoology

Applied zoology deals with the study of animals with economic or practical results. In this sense, zootechnics is about the breeding and multiplication of animals, as well as the production of their derivatives, such as milk, taking into account the welfare of the animal.


The zoo is a space with adequate infrastructure to maintain, care for and breed different species of animals, and so that it can be visited by the public. It also has trained personnel to provide medical treatment to sick animals and for the conservation of endangered species.
