Acanthion is a subgenus of Old World porcupines in the genus Hystrix . It contains two species, H. javanica and H. brachyura, the smaller species with comparatively smaller nasals. The extant species have only one black ring or coloured part on the quills. [1]
Porcupines are large rodents with coats of sharp spines, or quills, that protect them against predation. The term covers two families of animals: the Old World porcupines of family Hystricidae, and the New World porcupines of family Erethizontidae. Both families belong to the infraorder Hystricognathi within the profoundly diverse order Rodentia and display superficially similar coats of rigid and/or semi-rigid quills which are modified hairs composed of keratin. Despite this, the two groups are distinct from one another and are not closely related to each other within the Hystricognathi. The largest species of porcupine is the third-largest living rodent in the world after the capybara and beaver.
The Old World porcupines, or Hystricidae, are large terrestrial rodents, distinguished by the spiny covering from which they take their name. They range over the south of Europe and the Levant, most of Africa, India, and the maritime Southeast Asia as far east as Flores. Although both the Old World and New World porcupine families belong to the infraorder Hystricognathi of the vast order Rodentia, they are quite different and are not particularly closely related.
The Indian crested porcupine is a hystricomorph rodent species native to southern Asia and the Middle East. It is listed as Least Concern on the IUCN Red List. It belongs to the Old World porcupine family, Hystricidae.
Hystrix is a genus of porcupines containing most of the Old World porcupines. Fossils belonging to the genus date back to the late Miocene of Africa.
The crested porcupine also known as the African crested porcupine, is a species of rodent in the family Hystricidae found in Italy, North Africa, and sub-Saharan Africa.

Siphonaria is a genus of air-breathing sea snails or false limpets, marine pulmonate gastropod molluscs in the family Siphonariidae, the false limpets.
The Malayan porcupine or Himalayan porcupine is a species of rodent in the family Hystricidae. Three subspecies are extant in South and Southeast Asia.
The Sunda porcupine is a species of rodent in the family Hystricidae. It is endemic to Indonesia. Due to the popularity of the hunting and consumption of the Sunda porcupine as an aphrodisiac, the Ministry of Environment and Forestry in Indonesia has listed this species as a protected animal as of June 2018.
Ratanakiri Province in northeastern Cambodia is home to many species of animals. One 1996 survey of an area to the northwest of Lomphat Wildlife Sanctuary recorded 44 mammals, 76 birds, and 9 reptile species. The following is an incomplete list of species recorded in Ratanakiri.

The Mammalia in the 10th edition of Systema Naturae forms one of six classes of animals in Carl Linnaeus's tenth reformed edition written in Latin. The following explanations are based on William Turton's translations who rearranged and corrected earlier editions published by Johann Friedrich Gmelin, Johan Christian Fabricius and Carl Ludwig Willdenow:
Animals that suckle their young by means of lactiferous teats. In external and internal structure they resemble man: most of them are quadrupeds; and with man, their natural enemy, inhabit the surface of the Earth. The largest, though fewest in number, inhabit the ocean.
Trachodes is a genus of true weevils in the family of beetles known as Curculionidae. There are at least 30 described species in Trachodes.
Hystrix primigenia is an extinct species of Old World porcupine that lived during the Late Miocene and Pliocene. Fossils of this species were recovered mainly from southern Europe, from Spain to Turkey and North Africa as well. The earliest fossils were found in Greece and the Balkan peninsula.
