Living lemurs range in weight from the 30-gram (1.1 oz) mouse lemur to the 9-kilogram (20 lb) indri. Since the arrival of humans on the island around 2,000 years ago, over a dozen species of "giant lemurs" larger than living lemur species have become extinct, including the gorilla-sized Archaeoindris.
The ring-tailed lemur was one of the first lemurs to be classified, by Carl Linnaeus in 1758.. Lemurs were first classified in 1758 by Carl Linnaeus, and the taxonomy remains controversial today, with approximately 70 to 100 species and subspecies recognized, depending on how the term "species" is defined.
Delacour's langur is somewhat larger than its two closest relatives, François' langur and the Laotian langur, but in other respects has a similar appearance.Adults measure from 57 to 62 cm (22 to 24 in) in head-body length, with a tail 82 to 88 mm (3.2 to 3.5 in) long.
The Sunda flying lemur (Galeopterus variegatus), also called Malayan flying lemur and Malayan colugo is the sole colugo species of the genus Galeopterus. [1] It is native to Southeast Asia from southern Myanmar, Thailand, southern Vietnam, Malaysia to Singapore and Indonesia and listed as Least Concern on the IUCN Red List. [2]
An ancestral lemur population is thought to have inadvertently rafted to the island on a floating mat of vegetation, although hypotheses for land bridges and island hopping have also been proposed. The timing and number of hypothesized colonizations has traditionally hinged on the phylogenetic affinities of the aye-aye , the most basal member ...
The Cat Ba langur (Trachypithecus poliocephalus), also known as the golden-headed langur, is a critically endangered species of langur endemic to Cát Bà Island, Vietnam.It is among the rarest primates in the world, and possibly the rarest primate in Asia, with population size estimated at less than 70 individuals.
Most species are highly agile, and regularly leap several metres between trees. They have a good sense of smell and binocular vision. Unlike most other lemurs, all but one species of lemurid (the ring-tailed lemur) lack a tapetum lucidum, [7] a reflective layer in the eye that improves night vision. Historically among mammals, activity cycles ...
