Hylobates lar: Lar gibbon

The lar gibbon [Hylobates lar], also known as the white-handed gibbon, is a primate in the gibbon family, Hylobatidae. It is one of the better-known gibbons and is often seen in zoos.

The fur coloring of the lar gibbon varies from black and dark-brown to light-brown, sandy colors. The hands and feet are white-colored, likewise a ring of white hair surrounds the black face. Both males and females can be all color variants, and the sexes also hardly differ in size. Gibbons are true brachiators, propelling themselves through the forest by swinging under the branches using their arms. Reflecting this mode of locomotion, the white-handed gibbon has curved fingers, elongated hands, extremely long arms and relatively short legs.

The common squirrel monkey [Saimiri sciureus] is a small New World primate from the Cebidae [squirrel monkey] family, and native to the tropical areas of South America.

The common squirrel monkey can be found primarily in the Amazon Basin, including territories in the countries of Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, Paraguay and Venezuela; a small population has been introduced to Southern Florida and many of the Caribbean Islands. The common squirrel monkey prefers to live in the middle canopy, but will occasionally come to the ground or go up into the high canopy. They like vegetation that provides good cover from birds of prey in the rainforest, savannah, mangroves, or marshlands.

The squirrel monkey’s tail is not prehensile but it used in balancing as the animal jumps through the trees. Their body length is about 32cm [12.5 inches] with a slightly longer tail 41cm [16 inches]. Males are heavier [750g] than females [500g]. Their coat is short, greyish or olive in colour except for its bright yellow-orange legs. Its white face has a peak of dark fur on the forehead and a dark muzzle.

Spider Monkeys get their name from the spidery length of their limbs, including the long, prehensile tail. Their long arms and legs and a prehensile tail that acts like a fifth limb making them exceptionally agile. The tail has a hairless patch on the tip that’s used for grip. When swinging by the tail, the hands are free to gather food. Spider monkeys have no thumbs as they are unnecessary for swinging through trees.
