Size and Description
are part of a group that has claws/digits. They have a nail on the big toe
only. Pygmy marmosets
are the smallest primates in the world. New born babies weigh only half
of an ounce. In two years they reach adult size and maturity, weighing three
ounces. A full grown adult can weigh up to five ounces (which is over 130
grams). The body length is between 130 to 370 mm [5-14 inches] and its tail
is between 150 and 420 mm [6-15 inches]. The forelimbs are shorter than
the hind limbs.
fur on the pygmy marmoset
is thick, and the under side is usually orangish, although it can range
from white or tawny. The tufts of hair that looks like a mane are usually
dark brown or gray. The long tail of a pygmy
marmoset is ringed, but not prehensile.
marmosets have two molars,
but most other monkies have three. Pygmy
marmosets are short-tusked or have
only slightly longer canines than incisors.
There is nowhere that says they have wisdom teeth so we can conclude that
they do not. Except for their genitals,
of different sexes are similar in appearance. The eyes of pygmy
marmosets are hazel and brown, they
only vary slightly.
are actually the largest of something! They have the largest birth weight
compared to the mother, of any monkey. Think of humans for example, the
average woman weighs 150, and the average baby weighs about 8 pounds.
That is about a 19th of the woman's weight. The baby pygmy
is only a 6th of the Adult pygmy's weight.
Now to see how
small Pygmy Marmosets really are, here are two pictures of their skulls!
Gross, I know, but see that quarter by the skull? They are really small.But
look at how big the cavity is where their brain goes! They have big brains
in those little heads.
