The indri (/ ˈ ɪ n d r i / ⓘ; Indri indri), also called the babakoto, [8] is one of the largest living lemurs, with a head-body length of about 64–72 cm (25– 28 + 1 ⁄ 2 in) and a weight of between 6 and 9.5 kg (13 and 21 lb). It has a black and white coat and maintains an upright posture when climbing or clinging.
Archaeoindris fontoynontii is an extinct giant lemur and the largest primate known to have evolved on Madagascar, comparable in size to a male gorilla.It belonged to a family of extinct lemurs known as "sloth lemurs" (Palaeopropithecidae) and, because of its extremely large size, it has been compared to the ground sloths that once roamed North and South America.
The extinction of the largest lemurs is often attributed to predation by humans and possibly habitat destruction. [2] Since all extinct lemurs were not only large (and thus ideal prey species), but also slow-moving (and thus more vulnerable to human predation), their presumably slow-reproducing and low-density populations were least likely to ...
Some lemur species have extensive vocal repertoires, including the ring-tailed lemur and ruffed lemurs. [89] [117] Some of the most common calls among lemurs are predator alarm calls. Lemurs not only respond to alarm calls of their own species, but also alarm calls of other species and those of non-predatory birds.
This is a list of large extant primate species (excluding humans) that can be ordered by average weight or height range. There is no fixed definition of a large primate, it is typically assessed empirically. [1]
At 8 kilometres (5 mi) across, and estimated at 100,000 years old, [3] it may be one of the largest and oldest clonal colonies on Earth. [4] [5] [6] Among animals, the largest species are all marine mammals, specifically whales. The blue whale is believed to be the largest animal to have ever lived. [7]
Archaeoindris was the largest of the sloth lemurs, and the largest known lemur. It weighed approximately 160 kg (350 lb). Sloth lemurs. The sloth lemurs (family Palaeopropithecidae) were the most species-rich group of the subfossil lemurs, with four genera and eight species.
Primates is a diverse order of placental mammals which includes monkeys, lemurs, galagos, lorisids, tarsiers, and apes (including humans). Members of this order are called primates. The order currently comprises 505 extant species, which are grouped into 81 genera. The majority of primates live in South and Central America, Africa, and southern ...
