Smallest Primates: Pygmy marmosets are often called the world's smallest primates due to their diminutive size, with an average length of about 4.6 to 6.2 inches (12 to 16 centimeters).
Gum Feeding: They are specialized gum-feeders, and their diet primarily consists of tree gum, sap, and resin. They use sharp teeth to gouge holes in tree bark and then lick up the oozing gum.
Acrobatic Agility: These tiny primates are known for their incredible agility in the treetops. They can leap up to 16 feet (5 meters) between branches.
Multiple Births: Pygmy marmosets usually give birth to twins, but they can also have singletons or occasionally triplets. This is relatively unusual among primates.
Short Lifespan: In the wild, pygmy marmosets have an average lifespan of around 6 to 9 years. However, they can live longer in captivity, with some individuals reaching 15 years or more.
