This is a list of the native wild mammal species recorded in Mexico.As of September 2014, there were 536 mammalian species or subspecies listed. Based on IUCN data, Mexico has 23% more noncetacean mammal species than the U.S. and Canada combined in an area only 10% as large, or a species density over 12 times that of its northern neighbors.
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
Although the tapetum is considered to be ubiquitous in lemurs, there appear to be exceptions among true lemurs, such as the black lemur and the common brown lemur, as well as the ruffed lemurs. [ 16 ] [ 32 ] [ 88 ] Since the riboflavins in the tapetum have a tendency to dissolve and vanish when processed for histological investigation, however ...

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 ...
According to genetic studies, the lemurs of Madagascar diverged from the lorisoids approximately 75 mya. [40] These studies, as well as chromosomal and molecular evidence, also show that lemurs are more closely related to each other than to other strepsirrhine primates. [40] [46] However, Madagascar split from Africa 160 mya and from India 90 ...
Some of their adaptations were unlike those seen in lemurs today. [25] All 17 extinct lemurs were larger than the extant forms, some weighing as much as 200 kg (440 lb), [41] and are thought to have been active during the day. [66] Not only were they unlike the living lemurs in both size and appearance, they also filled ecological niches that ...
In isolation, the lemurs diversified and filled the niches often filled by monkeys and apes today. [14] In Africa, the lorises and galagos diverged during the Eocene, approximately 40 mya. [11] Unlike the lemurs in Madagascar, they have had to compete with monkeys and apes, as well as other mammals. [15]
