Hylobates lar Skull Replica measures 4.3 inches. Hylobates lar Skull Replica is museum quality polyurethane cast. 2-part skull (separate cranium and jaw). Made in USA. Cast is an original California Academy of Sciences. Known as the White-handed Gibbon. Our precise skull can be used as a teaching tool, museum skull exhibit, home decor skull, or office decor skull.

The White-handed Gibbon or Hylobates lar are dichromatic in pelage. They wear either a dark coat, which may range from gray to black to brown, or a light coat of light cream color to light brown.

The hairless face is surrounded by a ring of very short white or lightly colored fur; and the hands and feet are both white.

Hylobates lar elongated forelimbs, hands, and feet are adaptations for brachiation, which is their primary mode of travel through forest canopie.  White-handed gibbon monkey or Hylobates lar do not have tails.

The Lar gibbon, also known as the White-handed Gibbon, is an endangered primate in the gibbon family, Hylobatidae. It is one of the better-known Gibbons and is often kept in captivity.

Hylobates lar are largely frugivorous animals, eating ripe fruit from woody climbers and tropical trees. They also eat leafy plants, flowers, and insects, and are very selective feeders when it comes to fruit consumption.

Fruits are tasted and either accepted or rejected based on ripeness. The same food sources are returned to multiple times during peak season to eat the ripest fruit each time. Food sources are also shared in overlapping territory areas.

Hylobates lar rarely come to the ground, instead using their long arms to brachiate through the trees. With their hooked hands, they can move swiftly with great momentum, swinging from the branches.

Although they rarely come to the ground naturally, while there, they walk bipedally with arms raised above their heads for balance.

Reflecting this mode of locomotion, the White-handed Gibbon has curved fingers, elongated hands, extremely long arms and relatively short legs, giving it an intermembral index of 129.7, one of the highest of the primates.

As with all apes, the number of caudal vertebrae has been reduced drastically, resulting in the loss of a functional tail. Gibbons have tough, bony padding on their buttocks, known as the ischial callosities, or sitting pads.

Hylobates lar social organization is dominated by monogamous family pairs, with one breeding male and one female along with their offspring.
