Is the lovely Goeldi's monkey a tamarin or a marmoset? Neither!
Tamarins average 17 inches in length, live in groups of up to 40 individuals, and have long canines for eating insects and fruits.
Marmosets max out at around 15 inches, live in smaller groups of up to 15 individuals, and have large pointy incisors for chewing through tree bark.
Goeldi's monkeys are the only members of the genus callimico, and they set themselves apart in a few ways:
Their diets are seasonal, and at the right time of year they rely heavily on mushrooms as a food source.
They only have one baby at a time, where tamarins and marmosets have twins or ocassionally triplets.
They have 3 molars where tamarins and marmosets have 2.
Callimico fathers are not as involved in child rearing as tamarins and marmosets.
They have the largest range, living in southern Colombia, eastern Ecuador and Peru, western Brazil and northern Bolivia.
These unique creatures are a true treat!
