One thing I love to admire about primates is the similarities between us. To their similarly built hands and feet, and expressive personalities. The fingers, nails, toes, ears, and facial structure are like that of our fellow humans.
White-Cheeked Gibbon Monkey
The northern white-cheeked gibbon (Nomascus leucogenys) is a Critically Endangered species of gibbon native to South East Asia. It is closely related to the southern white-cheeked gibbon (Nomascus siki), with which it was previously considered conspecific. The females of the two species are virtually indistinguishable in appearance.
The genome of N. leucogenys was sequenced and published in 2011.
The white-faced saki (Pithecia pithecia), called the Guianan saki and the golden-faced saki, is a species of the New World saki monkey. They can be found in Brazil, French Guiana, Guyana, Suriname and Venezuela. This species lives in the understory and lower canopy of the forest, feeding mostly on fruits, nuts, seeds, and insects. Although they are arboreal creatures and are specialists of swinging from tree to tree (brachiation), they are also terrestrial when foraging. White-faced sakis typically live around 14 years in their natural habitat and have been recorded to live up to 36 years in captivity. Sakis are active in the day and sleep highly elevated (15-20m) in trees with many leaves to shelter them from weather and flying predators.
The ring-tailed lemur (Lemur catta) is a large strepsirrhine primate and the most recognized lemur due to its long, black and white ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the Lemur genus. Like all lemurs it is endemic to the island of Madagascar and endangered. Known locally in Malagasy as maky ([makʲ] (
listen), spelled maki in French) or hira, it inhabits gallery forests to spiny scrub in the southern regions of the island. It is omnivorous and the most terrestrial of extant lemurs. The animal is diurnal, being active exclusively in daylight hours.
Coquerel's sifaka (Propithecus coquereli) is a diurnal, medium-sized lemur of the sifaka genus Propithecus. It is native to northwest Madagascar. Coquerel's sifaka was once considered to be a subspecies of Verreaux's sifaka, but was eventually granted full species level, and is listed as endangered due to habitat loss and hunting. In popular culture, it is known for being the species of the title character in the children's TV show Zoboomafoo. The species was named after French entomologist Charles Coquerel.
