1.Indri's relations to similar animals found in other locations?

It lives primarily in the canopy, and rarely, if ever, steps onto the ground floor. Lemurs are prosimians, one of the more primitive types of primate. I looked in books and on many websites and still don't understand. In fact, the main reason they are endangered (most of them) is due to human actions and not their inability to survive in their natural environment. Animals that have already produced enough young or those that are hybrids between subspecies cannot be used for species survival plan (SSP) breeding are considered ... a long neck and large ears are adaptation of both the serval and the maned wolf for _____. Genera of the Indriidae (Propithecus and Indri) are also predominantly leapers; even though they are equally capable as bushbabies or tarsiers to jump across considerable gaps between trees and branches, these large diurnal prosimians do not share the foot adaptation characteristic for galagos and tarsiers. Cold adaptation is of three types: adaptation to extreme cold, moderate cold, and night cold. All the different species of Lemurs have different ways of surviving.
Predator Adaptations It is the largest carnivore and top predator native to Madagascar and is known to feed on lemurs and most other creatures it can get its claws on, from wild pigs to mice.

It feeds on the fruits and leaves that grow within the canopy layer.

In addition, it addresses issues of primate behavioral ecology and how environment can play a major role in explaining species variation.

Adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations. As an adaptation to survival in a harsh climate, ring-tails range far and feed from a wide variety of vegetation. Despite their different sizes, however, lemurs have a lot in common.

Int J Primatol 24(6): 1143-62. Climatic adaptation, in physical anthropology, the genetic adaptation of human beings to different environmental conditions. Powzyk JA, Mowry CB. Tobi gives a good answer. Adaptations occur over time and are driven by an increased survival of offspring with a certain advantageous trait.

Sifakas are beautifully colored. They can leap several feet in order to get to food and to avoid predators. They have been able to successful adapt to changes in their environment.

The indri is known locally as babakoto, which translates to "Ancestor of Man".

The Indri is also a very vocal creature, best known for the haunting song it sings. They may have different colored limbs and bodies, and often their heads are multicolored with patches of black, white, gray, or golden-colored fur.
