They include the following genera: *''Heterodon'', which occur mainly in the United States and northern Mexico *'' Leioheterodon'', the hognose snakes native to Madagascar *''Lystrophis'', the South American hognose snakes. The North American ''Heterodon'' species are known for their habit of thanatosis: playing dead when threatened.

Heterodon Nasicus
The western hognose snake (''Heterodon nasicus'') is a species of snake in the family Colubridae. The species is endemic to North America. There are three subspecies that are recognized as being valid, including the nominotypical subspecies. Etymology The specific name, ''nasicus'', is derived from the Latin '' nasus'' ("nose"), a reference to the snake's upturned snout. The dusky hognose's subspecific name, ''gloydi'', is in honor of American herpetologist Howard K. Gloyd (1902–1978). Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. Baltimore. xiii + 296 pp. . (''Heterodon nasicus gloydi'', p. 102; ''Heterodon nasicus kennerlyi'', p. 140). The Mexican hognose's subspecific (or specific) name, ''kennerlyi'', is in honor of American naturalist Caleb Burwell Rowan Kennerly. Common names Common names for ''Heterodon nasicus'' include blow snake, bluffer, plains hognose snake, prairie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterodon Platirhinos
The eastern hog-nosed snake (''Heterodon platirhinos''), is a species of mildly venomous rear-fanged snake in the family Colubridae. The venom is specifically adapted to amphibian prey and is harmless to humans. However, some people may have an allergic reaction, and experience local swelling and other symptoms. The species is endemic to North America. There are no subspecies that are recognized as being valid. This species prefers habitats with sandy soils and a combination of grass fields and forest edges. They come in many different colorations and have the identifiable upturned "snout". They can be found in captivity but are a relatively difficult species to keep due to a specialized diet of toads. As with other ''Heterodon'' species, they have a distinctive threat reaction of first bluffing by striking with a closed mouth and then pretending to die if this fails to deter the threat. Geographic range ''H. platirhinos'' has a wide geographical range from the central United Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Heterodon'' is a genus of harmless colubrid snakes endemic to North America.Platt, Dwight R. 1983. Heterodon'. Catalogue of American Amphibians and Reptiles.

Leioheterodon Madagascariensis
''Leioheterodon madagascariensis'', the Malagasy, Madagascar or Madagascan giant hognose (snake), is a harmless species of pseudoxyrhophiid snake endemic to the island nation of Madagascar. The species is also found on the country's smaller islands of Nosy Be, Nosy Mangabe, and Nosy Sakatia, as well as on the Comoros archipelago, in the Mozambique Channel. It is thought, by some, to have been introduced to the Grande Comoro. Mature giant hognose snakes can measure between 130 and 180 cm (4 ft. to nearly 6 ft., or between 1-2 meters) in length, and be roughly the thickness of an average adult human's arm. Similarly to the ''Heterodon'' or ''Lystrophis'' genera of new-world hognoses, the Madagascar giant hognose, when threatened, will raise its head, open its mouth and inflate the skin around its neck and chin, superficially mimicking a cobra (or even a bearded dragon) in defensive posture, in an attempt to look larger and more intimidating.
