Gaoligong pika
The Gaoligong pika (''Ochotona gaoligongensis'') is a species of mammal in the Ochotonidae family. It is endemic to China. Many of the general physical characteristics of the pika species, are shared by Gaoligong pikas. However, the Gaoligong pika is specifically characterized by unique physical characteristics, including a red-brown colored crown around the neck and black behind the ears. They can produce one litter per year and can live up to three years. Their behavior is currently undetermined due to limited information available about the species. This is due to the inaccessibility of their habitat.
==Evolution and classification==
The Ochotonidae family includes over 30 different species of territorial, small-bodied herbivore species of pikas, including the Gaoligong pika. Because of their resemblance and similar characteristics, pikas are considered to have diverged from the same lineage as that of the Leporidae. There are evolutionary appearances that have been connected to each specific group of pikas within the family, during the Pliocene and Pleistocene periods. Ochotonids share very similar physical characteristics, which have made it nearly impossible to order them according to their taxonomy. However, there are three main subgroups of pikas, in which each classification of Pikas has been organized based on their location and physical characteristics. Particularly for the Gaoligong pika, their classification falls under the subgroup of mountain pikas.〔 This classification extends far into the subgenus of the Conothoa, which is one of the three main subgenera each subgroup is divided into. The appearance of the Gaoligong pikas is dated back to the late Pliocene period, where other Ochotona species emerged, including but not limited to: ''Ochotona brookei'', ''Ochotona forresti'', ''Ochotona gloveri'', and ''Ochotona himalayana''. Within the pika group, there is high exhibition of intraspecific morphological diversity versus low interspecific diversity, thus the emergence of several subgroups. The emergence of different types of species, including the Gaoligong pika and those unknown today, have been traced back to the appearance of the K/T boundary, making the Ochotonidae family less rich in species when compared to other families of the superorder Glires.
