The Zoo is called a man-made artificial habitat where wild and domesticated animals are kept. Different zoos have been built in different cities in Iran, some of which are home to different animals, some of which include more restricted and specialized species.
The overall goal is to gather living animals in an environment similar to the natural habitat, to create a healthy environment for leisure time, especially for children and adolescents, to connect nature and urban life, to create a sense of interest in nature and biodiversity, and to raise public awareness and to stimulate public opinion about recognizing part of the natural resources and to create incentives to protect it.
You don't have to travel around the world to see most beautiful and rare species of the world's fish. Just go to the collection of aquariums made in Iran. Where it holds more than thousands of marine life.
