[7] The Sun-tailed monkey is a Class B protected species under the African Convention and Appendix II of CITES.

Around 10% of the monkey's habitat is in the Lopé National Park, but the highest density is at the Foret des Abeilles, which is still unprotected.

It is recommended that there should be more monitoring of hunting and logging activity in its habitat, as well as more research into the distribution and biology of the species in general.

As one of the most poorly known nonhuman primate species with only one semi-captive population in the world, not much is known about its genome or biochemistry.

Blood analysis of the sun-tailed monkey reveals that males show higher levels of hemoglobin and hematocrit than females.
