  • Crotalus Cerastes, the Sidewinder
    180 / Litteratura Serpentium, 1993, Vol. 13, Nr. 6 CROTALUS CERASTES, THE SIDEWINDER By: Pete Strimple, 5310 Sultana Drive, Cincinnati, Ohio 45238, U.S.A. Contents: Historical -Habitat- Food -Habits -Breeding- The subspecies of Crotalus cerastes - Key to the subspecies of Crotalus cerastes. * * * HISTORICAL The sidewinder is a small to intermediate sized rattlesnake found in the southwestern United States and northwestern Mexico. It was first described by Hallowell in 1854 as Crotalus cerastes. The type specimen was collected by Dr. A.L. Heerman, with the type locality being designated as 'borders of the Mojave River, and in the desert of the Mojave (California).' In 1944, Laurence Klauber described the first subspecies based on a specimen collected at the Narrows, San Diego County, California. Klauber named the subspecies Crotalus cerastes laterorepens, the Colorado Desert sidewinder. The subspecies name 'laterorepens' is quite fitting for a sidewinder, because it is latin for 'sideways creeping.' In accordance with the rules of nomenclature, this established the nominate subspecies as Crotalus cerastes cerastes Hallowell, the Mojave desert sidewinder. These remained the only two subspecies of the sidewinder until 1953, when Savage and Cliff described Crotalus cerastes cercobombus, the Sonora sidewinder. The subspecies name 'cercobombus' is actually a combination of a Greek and Latin word which mean 'buzzing tail.' HABITAT Crotalus cerastes is primarily a desert dwelling form, whose habitats include desert flatland, sand dunes, and sand hammocks topped with creosote or mesquite bushes. FOOD Sidewinders feed mainly on small mammals (kangaroo rats, mice, pocket gophers, etc.) and lizards (desert iguanas, utas, whiptails, etc.). There are also records of sidewinders eating birds, and even a case of cannibalism.

  • (Crotalus Oreganus Helleri) Hunting Behavior Through Community Science
    diversity Article Quantifying Southern Pacific Rattlesnake (Crotalus oreganus helleri) Hunting Behavior through Community Science Emily R. Urquidi * and Breanna J. Putman Department of Biology, California State University San Bernardino, 5500 University Parkway, San Bernardino, CA 92407, USA; [email protected] * Correspondence: [email protected] Abstract: It is increasingly important to study animal behaviors as these are the first responses organisms mount against environmental changes. Rattlesnakes, in particular, are threatened by habitat loss and human activity, and require costly tracking by researchers to quantify the behaviors of wild individuals. Here, we show how photo-vouchered observations submitted by community members can be used to study cryptic predators like rattlesnakes. We utilized two platforms, iNaturalist and HerpMapper, to study the hunting behaviors of wild Southern Pacific Rattlesnakes. From 220 observation photos, we quantified the direction of the hunting coil (i.e., “handedness”), microhabitat use, timing of observations, and age of the snake. With these data, we looked at whether snakes exhibited an ontogenetic shift in behaviors. We found no age differences in coil direction. However, there was a difference in the microhabitats used by juveniles and adults while hunting. We also found that juveniles were most commonly observed during the spring, while adults were more consistently observed throughout the year. Overall, our study shows the potential of using Citation: Urquidi, E.R.; Putman, B.J. community science to study the behaviors of cryptic predators.

  • A Crowned Devil: New Species of Cerastes Laurenti, 1768 (Ophidia, Viperidae) from Tunisia, with Two Nomenclatural Comments
    Bonn zoological Bulletin Volume 57 Issue 2 pp. 297–306 Bonn, November 2010 A crowned devil: new species of Cerastes Laurenti, 1768 (Ophidia, Viperidae) from Tunisia, with two nomenclatural comments Philipp Wagner1* & Thomas M. Wilms2 1 Zoologisches Forschungsmuseum Alexander Koenig, Adenauerallee 160, 53113 Bonn, Germany; [email protected] 2 Zoologischer Garten Frankfurt, Bernhard-Grizmek-Allee 1, 60316 Frankfurt a. Main, Germany; * corresponding author Abstract. A distinctive new species of the viperid genus Cerastes is described form Tunisia. It is closely related to Cerastes vipera but easily distinguishable from this invariably hornless species by having tufts of erected supraocular scales form- ing little crowns above the eyes. These crown-like tufts consist of several vertically erect, blunt scales which differ dras- tically from the supraocular horns of C. cerastes or C. gasperettii that consist of one long, pointed scale only. Although the new species is based on only one single specimen, further specimens had originally been available but were subse- quently lost in private terraria. The taxonomic status of the nomen “Cerastes cerastes karlhartli” is discussed and the name is found to be unavailable (nomen nudum). Also the authorship of “Cerastes cornutus” is discussed and ascribed to Boulenger. Key words. Cerastes cerastes, Cerastes vipera, Cerastes sp. n., Cerastes c. karlhartli, Cerastes cornutus, horned viper, North Africa, Tunisia. INTRODUCTION The genus Cerastes Laurenti, 1768 includes only five taxa The second North African species is C. vipera (Linnaeus, (three species and two subspecies), which are distributed 1758). Its distribution range is very similar to C. cerastes in northern Africa and on the Arabian Peninsula.

Ryan, Area Specialist, Natural Resources, University of Nevada Cooperative Extension Updated from G. Mitchell, M.L. Robinson, D.B. Hardenbrook and E.L. Sellars. 1998. What’s the Buzz About Nevada’s Venomous Reptiles? University of Nevada Cooperative Extension—Nevada Department of Wildlife Partnership Publication. FS-98-35. SP 07-07 (Replaces FS-98-35) NEVADA’S REPTILES Approximately 52 species of snakes and lizards share the Nevada landscape with us. Of these, only 12 are considered venomous. Only 6 can be dangerous to people and pets. Encountering them is uncommon because of their body camouflage and secretive nature, which are their first defenses in evading predators. Consider yourself fortunate if you do see one! As with all wildlife, treat venomous reptiles with respect. Reptiles are ectothermic, meaning their body temperature increases or decreases in response to the surrounding environment. They are most active in the spring, summer and early fall when it’s comfortable, short sleeve weather for us. Reptiles usually hibernate, or brumate, in winter in response to colder temperatures. During high summer temperatures in the Mojave Desert, reptiles may spend time underground in order to maintain vital body temperatures. In most cases*, collecting Nevada’s native reptiles is not allowed without the appropriate permit, which is issued by the Nevada Department of Wildlife.
