Step-by-step explanation:
The main aim of researching these animals is to discover why they are becoming extinct. The results of this research help zoologists to better cater to the need of the animals, protect them and create a realistic conservation plan. Some of the information identified during research may include, diseases they are susceptible to and how to cure them, the science behind their procreation and how to enhance or improve reproduction of these species, etc.
