THE NATURE OF SNAKES WESTERN DIAMONDBACK RATTLESNAKE THE MOST HIGHLY EVOLVED SNAKES ON OUR PLANET WHEN THEY HUNT, THEY AMBUSH THEIR PREY. THEY SIT & THEY WAIT VERY STILL SOMETIMES FOR MANY HOURS SNAKES OF TEXAS 2. THE NATURE OF SNAKES WESTERN DIAMONDBACK RATTLESNAKE They hunt their prey using heat-sensing pits that do what their name implies: they help the snake sense heat. They can track their prey with their tongues & vaguely see them with their eyes, but it's their loreal pits that make up the difference SNAKES OF TEXAS 2.

SNAKE SPECIES IN TEXAS HOW DOES A SNAKE EAT A PREY SO MUCH LARGER THAN ITSELF? SNAKES OF TEXAS 3. SNAKE SPECIES IN TEXAS The Jacobson’s Organ • Snakes have also developed a highly a specialized scent organ known as the Jacobson organ, which allows them to literally taste & smell the air! SNAKES OF TEXAS 3. SNAKE SPECIS IN TEXAS The Jacobson’s Organ • The snake sends out his forked tongue & some of the moisture-laden smell particles lands on the tips of the fork. The snake flicks its tongue back inside where the Tips of its forked tongue can be dipped into the ducts from the Jacobson organ. SNAKES OF TEXAS 3. SNAKE SPECIES IN TEXAS The Jacobson’s Organ BRAIN NERVE JACOBSON’S ORGAN TONGUE This allows the snake to smell even more scents, things like pheromones and sweaty, stinky socks! SNAKES OF TEXAS 3. SNAKE SPECIES IN TEXAS There are 115 different snake species and sub-species found in the state of Texas but only 15 of those are venomous. SNAKES OF TEXAS MYTHS & MONSTERS SNAKES OF TEXAS MTYTHS & MONSTERS • Flower Mound, Texas (August 7, 2018)…. “Sunday night we were walking down on Cross Timbers Road & Auburn Road on the sidewalk, & there was a big copperhead and it was in ATTACK MODE. We ran back home because we didn’t have a flashlight”. SNAKES OF TEXAS MTYTHS & MONSTERS • The myths that snakes attack humans is born from this same fear. But it doesn’t make sense. A snake cannot eat a person. Biting someone is more often than not going to lead to the snake’s death as venom is not instantly lethal. SNAKES of TEXAS 4.

TALKING SNAKES Venomous Snakes of Texas THE PIT VIPERS • All of the snakes in this group (Rattlesnake, Cottonmouth and Copperhead) are members of the Viperidae family of snakes – PIT VIPERS for short. • The first part of the name, "pit," refers to the heat-sensing pits. • These pits are located about midway between the snake's eye and nostril. • The pits are thermoreceptors. They can detect differences in temperature, which helps the pit vipers locate their prey. SNAKES OF TEXAS Agkistrodon piscivorous 4. TALKING SNAKES THE PIT VIPERS • The heat sensing pits help the Pit Viper sense heat. The biggest use for “pits” is during hunting. Pit Vipers can track their prey with their tonges & Jacobson organ and Venom Hemo-Toxic vaguely see prey with their eyes, but it’s the loreal pits that make up a big difference. SNAKES OF TEXAS Agkistrodon piscivorous 4. TALKING SNAKES THE PIT VIPERS • Pits are sensitive to infrared radiation, which warm-blooded animals give off as heat. • This allows the pit viper to physically see their prey in tones of heat & cool so their can strike. Hemo-Toxic Venom Hemo-Toxic • Pit vipers also use their pit organs to help them find cool places to regulate their internal temperatures. SNAKES OF TEXAS Agkistrodon piscivorous 4. TALKING SNAKES Pit Viper WESTERN COTTONMOUTH (WATER MOCCASIN) • Also known as 'water moccasins', one recognized sub-species is found in Texas; The Western Cottonmouth, • Cottonmouths can be dark brown, olive-brown, olive green or almost solid black. They are marked with wide, dark bands, which are more distinct in some individuals than in others.. • The cottonmouth gets its name from the white tissue inside its Hemo-Toxic Venom Hemo-Toxic mouth, which it displays when threatened. • This heavy-bodied snake, which averages about 3-1/2 feet in length, is found over the central and eastern half of the state in swamps and sluggish waterways, coastal marshes, rivers, ponds and streams.

    Other Contributions NATURE NOTES Amphibia: Caudata Ambystoma ordinarium. Predation by a Black-necked Gartersnake (Thamnophis cyrtopsis). The Michoacán Stream Salamander (Ambystoma ordinarium) is a facultatively paedomorphic ambystomatid species. Paedomorphic adults and larvae are found in montane streams, while metamorphic adults are terrestrial, remaining near natal streams (Ruiz-Martínez et al., 2014). Streams inhabited by this species are immersed in pine, pine-oak, and fir for- ests in the central part of the Trans-Mexican Volcanic Belt (Luna-Vega et al., 2007). All known localities where A. ordinarium has been recorded are situated between the vicinity of Lake Patzcuaro in the north-central portion of the state of Michoacan and Tianguistenco in the western part of the state of México (Ruiz-Martínez et al., 2014). This species is considered Endangered by the IUCN (IUCN, 2015), is protected by the government of Mexico, under the category Pr (special protection) (AmphibiaWeb; accessed 1April 2016), and Wilson et al. (2013) scored it at the upper end of the medium vulnerability level. Data available on the life history and biology of A. ordinarium is restricted to the species description (Taylor, 1940), distribution (Shaffer, 1984; Anderson and Worthington, 1971), diet composition (Alvarado-Díaz et al., 2002), phylogeny (Weisrock et al., 2006) and the effect of habitat quality on diet diversity (Ruiz-Martínez et al., 2014). We did not find predation records on this species in the literature, and in this note we present information on a predation attack on an adult neotenic A. ordinarium by a Thamnophis cyrtopsis. On 13 July 2010 at 1300 h, while conducting an ecological study of A.

  • Xenosaurus Tzacualtipantecus. the Zacualtipán Knob-Scaled Lizard Is Endemic to the Sierra Madre Oriental of Eastern Mexico
    Xenosaurus tzacualtipantecus. The Zacualtipán knob-scaled lizard is endemic to the Sierra Madre Oriental of eastern Mexico. This medium-large lizard (female holotype measures 188 mm in total length) is known only from the vicinity of the type locality in eastern Hidalgo, at an elevation of 1,900 m in pine-oak forest, and a nearby locality at 2,000 m in northern Veracruz (Woolrich- Piña and Smith 2012). Xenosaurus tzacualtipantecus is thought to belong to the northern clade of the genus, which also contains X. newmanorum and X. platyceps (Bhullar 2011). As with its congeners, X. tzacualtipantecus is an inhabitant of crevices in limestone rocks. This species consumes beetles and lepidopteran larvae and gives birth to living young. The habitat of this lizard in the vicinity of the type locality is being deforested, and people in nearby towns have created an open garbage dump in this area. We determined its EVS as 17, in the middle of the high vulnerability category (see text for explanation), and its status by the IUCN and SEMAR- NAT presently are undetermined. This newly described endemic species is one of nine known species in the monogeneric family Xenosauridae, which is endemic to northern Mesoamerica (Mexico from Tamaulipas to Chiapas and into the montane portions of Alta Verapaz, Guatemala). All but one of these nine species is endemic to Mexico.

  • COTTONMOUTH Agkistrodon Piscivorus
    COTTONMOUTH Agkistrodon piscivorus Agkistrodon is derived from ankistron and odon which in Greek mean “fishhook” and “tooth or teeth;” referring to the curved fangs of this species. Piscivorus is derived from piscis and voro which in Latin mean “fish” and “to eat”. Another common name for cottonmouth is water moccasin. The Cottonmouth is venomous. While its bite is rarely fatal, tissue damage is likely to occur and can be severe if not treated promptly. IDENTIFICATION Appearance: The cottonmouth is a stout- bodied venomous snake that reaches lengths of 30 to 42 inches as adults. Most adults are uniformly dark brown, olive, or black, tending to lose the cross banded patterning with age. Some individuals may have a dark cheek stripe (upper right image). The cottonmouth has the diagnostic features of the pit-viper family such as a wedge-shaped head, sensory pits between the eyes and nostrils, and vertical “cat-like” pupils. Juveniles are lighter and more boldly patterned with a yellow coloration toward the tip of the tail (lower right image). Dorsal scales are weakly keeled, and the subcaudal scales form only one row. Cottonmouths also have a single anal Mike Redmer plate. Subspecies: There are three subspecies of the cottonmouth. The Western Cottonmouth (A. p. leucostoma) is the only subspecies found in the Midwest. The term leucostoma refers to the white interior of mouth. Confusing Species: The non-venomous watersnakes (Nerodia) are commonly confused with Cottonmouths across their range, simply because they are snakes in water. Thus it is important to note that Cottonmouths are only found in southernmost Midwest.

    MATOBO CONSERVATION SOCIETY CHECKLIST FOR THE HERPETOFAUNA OF THE MATOBO HILLS APPRECIATION This material was prepared by the MATOBO CONSERVATION SOCIETY from chapter 12 of the book “THE NATURAL HISTORY OF THE MATOBO HILLS” ISBN 978-0-7974-9815-0 with the approval of the NATURAL HISTORY MUSEUM OF ZIMBABWE The Matobo Conservation Society, a registered Welfare organisation, is committed to the conservation, appreciation and sustainable use of the natural and cultural resources within the Matobo Hills region. For more information (a) on this checklist and (b) the book “THE NATURAL HISTORY OF THE MATOBO HILLS”, write to: The Matobo Conservation Society, PO Box FM 648, Famona, Bulawayo or email [email protected] INTRODUCTION Compiled by Dr Don Broadley Sketches were done by Jenny Whalley The reptiles and amphibians together comprise the herpetofauna of the Matobo hills. It has a fairly rich species richness, consisting of 70 reptile and 28 amphibian species. Not only do these comprise a diverse assemblage, but they occur at very high densities compared to mammals. The herpetofauna of woodland and savanna areas of the Matobo includes many savanna species which are widely distributed across similar habitats of south-central Africa. With a few exceptions, most amphibians are seasonally dependant on surface water and the aquatic habitats in which it is localised. The permanent water bodies have a few characteristic reptile inhabitants. The serrated hinged terrapin is found in such dams and permanent streams, and is replaced in temporary pans by the helmeted terrapin. The water monitor is most plentiful around permanent water bodies, where it feeds largely on crabs and mussels.
