Western Hognose Snake Care Sheet (Heterodon Nasicus)
Western Hognose Snake Care Sheet (Heterodon nasicus) The western hognose snake is a small, stout bodied colubrid indigenous to north-central Mexico, central North America, and into south-central Canada. Hognose snakes are so named due to their pointed, upturned rostral (nose) scale that enable them to dig through sandy or other loose substrate in search of prey. Hognose snakes are well known for their defensive behaviors. When first encountered, they will produce a loud raspy hiss, flatten their heads and necks to mimic a cobra, and will mock strike in order to appear larger and more intimidating. If that display fails, hognose snakes will often flip themselves upside down and writhe about in the substrate with their mouth open in order to appear dead and lifeless to the predator while excluding a foul smelling musk. Western hognose snakes have become increasingly popular in the reptile industry due to their small size, and rodent eating habits when compared to other species of hognose. *Overall Difficulty Level: Novice Western hognose are a species that are suitable for the beginning reptile owner due to their small size and ease of care provided that one has a general knowledge of reptile, and specifically, snake husbandry. Unlike other North American hognose, captive born and well established western species adapt far more readily to eating rodents making them the most commonly and easily kept species of hognose. Given the proper care, western hognose snakes can attain longevity of 15-25 years on average in captivity. Western Hognose Taxonomy Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Squamata Suborder: Serpentes Family: Colubridae Subfamily: Xenodontinae Genus: Heterodon Species Epithet: Heterodon nasicus Size and Description Hatchling western hognose snakes typically range from five to nine inches in length. -

The bite from a brown recluse locally will resemble a target lesion but will develop into an ulcerative, necrotic lesion over time. Spider bites can be prevented by several simple measures including home cleanliness and wearing the proper attire while working outdoors. Although most spider bites cause only local tissue swelling, early species identification coupled with species-specific man- agement may decrease the rate of morbidity associated with bites. © 2011 Elsevier Inc.

Long-Term Effects of Snake Envenoming

We searched MEDLINE (from 1946) and EMBASE (from 1947) until October 2018 for clinical literature on the long-term effects of snake envenoming using different combinations of search terms. We classified conditions that last or appear more than six weeks following envenoming as long term or delayed effects of envenoming. Of 257 records identified, 51 articles describe the long-term effects of snake envenoming and were reviewed. Disability due to amputations, deformities, contracture formation, and chronic ulceration, rarely with malignant change, have resulted from local necrosis due to bites mainly from African and Asian cobras, and Central and South American Pit-vipers. Progression of acute kidney injury into chronic renal failure in Russell’s viper bites has been reported in several studies from India and Sri Lanka. Neuromuscular toxicity does not appear to result in long-term effects. -

Address correspondence to W. L. Smith at the address above, or e-mail: [email protected]. Abstract Knowledge of evolutionary relationships or phylogeny allows for effective predictions about the unstudied characteristics of species. These include the presence and biological activity of an organism’s venoms. To date, most venom bioprospecting has focused on snakes, resulting in six stroke and cancer treatment drugs that are nearing U.S. Food and Drug Administration review. Fishes, however, with thousands of venoms, represent an untapped resource of natural products. The first step in- volved in the efficient bioprospecting of these compounds is a phylogeny of venomous fishes. Here, we show the results of such an analysis and provide the first explicit suborder-level phylogeny for spiny-rayed fishes. The results, based on ;1.1 million aligned base pairs, suggest that, in contrast to previous estimates of 200 venomous fishes, .1,200 fishes in 12 clades should be presumed venomous. -

Wozniak DVM, PhD, Texas A&M University Health Science Center, Institute for Biosciences and Technology, Program for Animal Resources, 2121 W Holcombe Blvd, Houston, TX 77030 [email protected] ABSTRACT: Each year numerous emergency response personnel including animal control officers, police officers, wildlife rehabilitators, public health officers and others either respond to calls involving venomous snakes or are forced to venture into the haunts of these animals in the scope of their regular duties. North America is home to two distinct families of native venomous snakes: Viperidae (rattlesnakes, copperheads and cottonmouths) and Elapidae (coral snakes) and southeastern Texas has indigenous species representing both groups. While some of these snakes are easily identified, some are not and many rank amongst the most feared and misunderstood animals on earth. This article specifically addresses all of the native species of venomous snakes that inhabit Health Service Region 6/5s and is intended to serve as a reference to snake identification, field safety, basic safe capture and handling methods and the currently recommended first aide measures for reptile envenomation. -

Its snout is upturned with a ridge on the top. This snake may be yellow, brown, gray, olive, orange, or red. The back usually has dark blotches, but may be plain. A pair of large dark blotches is found behind the head. The underside of the tail is lighter than the belly. The scales are keeled (ridged). Its head shape is adapted for burrowing after hidden toads and it has elongated teeth used to puncture inflated toads so it can swallow them. Natural History The eastern hognose lives in areas with sandy or loose soil such as floodplains, old fields, woods, and hillsides. This snake eats toads and frogs. It is active in the day. It may overwinter in an abandoned small mammal burrow. It will flatten its head and neck, hiss, and inflate its body with air when disturbed, hence its nickname of “puff adder.” It also may vomit, flip over on its back, shudder a few times, and play dead. -
