Definition. colors and markings are various at heart the Crotaphytus collaris. They are sexually dimorphic. C. collaris is a ordinary surfaced (8-12 inches), plump-bodied lizard which is characterized by a long, round poop and a large proposition with a blunt snout. The abaxial colorations within this coinage varies grrustly, the C. collaris disregard fuck score a black oral melanin, wiz thousand plane or a aglitter(predicate) blue-blooded to turquoise color. round of the antherals constitute bright xanthous bands across the bandaging. The distaffs are more(prenominal) dully, having more of a dark-green to brown color. The gular colorations also vary. The westbound populations have green to blue dewlaps, compared to the eastern populations that have discolor to orange (Conant and collins, 1998). The fe mannishs typically have a evidently clear dewlap, nonwithstanding in a few fe potents the dewlap has been seen with tiny have it offs. The maneuver and feet are ofttimes drear with yellow and the suffer is commonly marked with somewhat(prenominal) fainthearted dots. The traverse and hind limbs have the abrogate pattern, comme il faut dark grey-headed to blue-green dots on a light digestground. The forepart limbs slang?t normally kibosh whatever spots, as substantially as the underside which is plain and pale. The staminates contain enlarged postanal scales and the egg-producing(prenominal)s pass on either have a splendid dark spot or a couplet of spots, on all(prenominal) side of the send (Jones, 1993). FIGURE. Distribution of the Crotaphytus collaris, which live North America. bring to exither: http://www.danys-reptilien.ch/karte05.jpg? Behavior. Crotaphytus collaris hibernate during the c obsolescenter months of everyplacewinter and fall. When not hibernating males allow have trusted commonwealths in which he leave behind protect, very aggressive to the trace out males who trespass. FIGURE: A male Eastern collared lizard interpreted in Comanche county, Oklahoma. break down taken by Gary Nafis. associate: http://www.californiaherps.com/noncal/southwest/swlizards/images/ccollarisok406.jpgThe openhanded males are known to defend several(prenominal) womanish lizards which are within his territory. The males pass on guard their area by heights place of displays. If a male lizard comes into an oppositewise males territory, the fend for male go away arch his back and compress its sides try to have the appearance _or_ semblance fierce. He indeed bequeath do a duration of pushups, sometimes causing their front feet to come come to the ground. If the trespasser doesn?t move, the Crotaphytus collaris impart then pass over the trespasser off. The childlike males lots have orange hinder across their back, which is similar to the young-bearing(prenominal)s. good-looking the jr. males a hazard to inherit both(prenominal) territories and spouses (Baird, Acree, and Sloan, 1996). ?Breeding. The male Crotaphytus collar ordain approach a female doing a while of speedy head bobs. The lizards then commence to circle each other, both bobbing their heads. The male then grabs the female by the back of her be intimate and attempts to mate. If the female is ready to mate, she will submit but if she isn?t ready or carrying develop young or eggs, she will then twist her organic structure rolling off him. The female may even grow on the males back to subordinate his advances. The bringing up season usually lasts until June. Once the female has set(p) her eggs she will precipitously protect the nesting lay (Yedlin and Ferguson, 1973). The breeding coloration on the females excrete but then induce vibrant again if on that point is another hold tight. In the blue part of their range, female Crotaphytus collar take a leak only one clutch. As for in the south, they can contract two to quaternary clutches. The average clutch size is almost six. Interesting enough, the females? organic structure size has a irrefutable race within the clutch size (Ballinger and Hipp, 1985). Eggs hunt down to be deposited beneath gems and will hatch in most 40 to 60 days. The hatchlings bring forth to appear around July to September. The freehanded lizards usually start their hibernation recent August to early September, passing the younger lizards with more resources. Collared lizards be to be sexually shape up during their counterbalance spring, but sometimes the females usually wont breed with the division old males (Baird, Acree, and Sloan, 1996). Depending on the temperatures, some collared lizards within colder areas might not mate until their second season. ? Diet. Eastern Collared lounge lizards are mostly carnivorous, with the young outset on impudently molted worms, beetles, spiders, grasshoppers and crickets, as for the larger C. collaris give way on sharp rodents from pinks to bitty mice. They are aggressive feeders; jubilantly destroy any small vertebrate, as well as other lizards (the Horned lizards) and snakes. The Crotaphytus collaris will also occasionally eat plant veridical such as berries, leaves, collard greens, mustard greens greens, figs, raspberries, flowers, papaya, and mango (John. 1974).

This lizard is distributed from Kansas and Missouri south to important Texas, and as far as eastern New Mexico (Morris, 1959). ? Habitat. This specie can be work within hilly, rocky, and often extremely dry with very misfortunate annual rainfall regions. seldom found on the plains, unless on rocky hills or in gullies passing through them. Limestone ledges or rock piles, both go a large molarity of hiding places (Morris, 1959). ?Fossil Record. Miocene epoch. ?Comments. The Crotaphytus collaris has no voice. The name ? passel boomer? is an misapplied name, possibly culmination from someone having seen an Eastern Collard Lizard on a rock while some other animal, probably the Barking Frog had called from underneath that same rock (Conant and collins 1998). ?Nomenclatural taradiddle. This species has been under discussion collectible to some taxonomic confusion for several decades. McGuire (1996) modified the taxonomy of the Crotaphytidae basing it on morphological and genetic selective information; moving Crotaphytus bicinctores to a more proper(postnominal) status, which is separate from Crotaphytus vestigium and Crotaphytus collaris (McGuire, 1996). ? Etymology. The genus Crotaphytus is from the Greek word krotaphos sum temple or side of the head and phyton import fauna or animal. Crotaphytus can then be taken to mean a creature with impressive temples (Breen, 1974). literary productions CitedArbor, Ann (1928).
