NHPs include simians (monkeys and apes) and prosimians (like lemurs). The most frequently used species are the long-tailed macaque and the rhesus monkey. In Europe, there is a trend towards using more New World monkeys and fewer prosimians. Great Apes have not been used in the EU since 2005.
A variety of NHP species are employed in research, each chosen for specific traits or similarities to human biology. The selection of species often depends on the research objectives, regulatory guidelines, and ethical considerations.
 
* '''Long-tailed Macaque (Macaca fascicularis):''' Among the most frequently used species in research, long-tailed macaques are particularly valuable in infectious disease studies and neuroscience research due to their physiological and genetic similarity to humans.
* '''Rhesus Monkey (Macaca mulatta):''' Another commonly used species, rhesus monkeys are integral in vaccine development, immune system studies, and behavioral research. Their well-understood genetic makeup makes them suitable for a wide range of biomedical studies.
* '''New World Monkeys:''' In Europe, there is an increasing trend towards using New World monkeys, such as marmosets and squirrel monkeys. These species are often used in neuroscience and behavioral studies. They offer distinct advantages in terms of their smaller size, unique physiological traits, and ethical considerations compared to larger primates.
* '''Prosimians:''' Including species like lemurs, prosimians are less commonly used but play a role in specific types of research, such as evolutionary biology and certain neurological studies.
* '''Great Apes:''' The use of Great Apes, like chimpanzees and gorillas, has significantly declined and is banned in many regions, including the European Union, due to ethical concerns and the availability of alternative research methods. When they were used, it was typically in critical research areas where no other suitable models were available.
 
Each species offers unique insights due to its specific biological traits. The choice of species is a critical decision in research planning, balancing scientific objectives with ethical implications and welfare considerations. This diversity not only reflects the complexity of biological research but also the ongoing efforts to refine, reduce, and replace the use of primates in research where possible.
