Pygmy marmosets are the world’s smallest monkey, growing to a full height of 14 to 16cm (excluding their 15 to 20cm tail) according to Wikipedia’s Pygmy Marmoset article.
These monkeys are truly adorable! This little guy here looks so sleepy. Don’t you just want to kiss him? Look at that sweet face!

In case you guys never heard of pygmy marmosets, what makes them special in particular, (aside from their undeniable cuteness), is their small size. Pygmy marmosets are the smallest existing monkeys. According to Wikipedia, they weigh between 120 and 140 grams (slightly over 1/4 of a pound). Imagine that. These two fuzzball marmosets are grooming each other. It looks like the bottom one is enjoying his own personal massage!
