The smallest monkey in the world

The smallest monkey in the world is the marmoset.

marmoset: also known as thumb monkey and short-toothed marmoset. It is the smallest monkey in the world that lives in the forests of the Amazon River basin in South America. Weighing only 5-12g, it is called "squirrel monkey" and "bird monkey" locally because of its small body, long tail and quick action, and it often runs around in the Woods and jumps freely. You need to eat insects regularly, otherwise it will be difficult to survive for a long time.

Marmosets have super eyesight. Thumb monkeys have very keen eyesight, and like humans, they can accurately judge the distance of objects with two eyes at the same time, so that they can jump and fly in the jungle and come and go freely. However, the thumb-fingered monkeys are not as good at color recognition as we are, and all male marmosets are red and green color blind. Interestingly, only some of the female marmosets are red and green color blind, and the other part has positive color vision like us.

Species value:

Marmosets are widely studied in the biomedical field, especially in reproductive biology, neuroscience, pharmacokinetics and drug toxicity screening, stem cell research, autoimmune diseases and animal models of infectious diseases, such as dengue fever.

At present, marmosets have been used as animal models in a variety of biological research, including neuroscience system research, assisted reproductive technology research, infectious diseases research and so on, especially many chronic diseases research, including Lassa fever, stroke, Parkinson's syndrome, multiple sclerosis, Huntington's chorea, Alzheimer's Harmo's disease and so on.
