The Wikipedia article of the day for December 20, 2016 is Strepsirrhini.
Strepsirrhini is a suborder of primates that includes lemurs from Madagascar, bushbabies and pottos from Africa, and lorises from India and southeast Asia. Also included are the extinct adapiform primates, a diverse and widespread group that thrived during the Eocene in Europe, North America, and Asia, but disappeared from most of the Northern Hemisphere as the climate cooled. Characterized by their wet nose or rhinarium, strepsirrhines have diversified to fill many ecological niches. They have a smaller brain than comparably sized simians, large olfactory lobes for smell, and a vomeronasal organ to detect pheromones. Their eyes contain a reflective layer to improve their night vision. Lemurs have a toothcomb, a specialized set of teeth in the lower front part of the mouth, mostly used for combing fur during grooming. Strepsirrhines are primarily tree-dwelling, feeding on fruit, leaves, and insects. Many are endangered by habitat destruction, poaching for bushmeat, and live capture for the exotic pet trade.
