The dragon was semi functional with locomotion being a bit shaky, one head and then the other leading the way. It was eating and defecating normally. One head (the smaller of the two) appeared to be doing all the eating. I fed it by pulling crickets apart so that they couldn't get away but were still moving. The lizard didn't seem interested in greens. Water was consumed by both heads when droplets were placed on the nose. It did fairly well for one month at which time mealworms were offered. The larger head became very active and ate a mealworm. Soon after that, it started going down hill.

to male interactions. Males are prone to injury from other males who are courting the same female, and who bite each other in attempt to dismount their rivals (Lutz & Musick, 57).
Other than the female coming Studentashore to nest, sea turtles spend their Reserve
After copUlation, the females return to their native beach to nest while males return to the foraging grounds. Nest site selection is a frequently studied event. Researchers attempt to analyze the nest site selections of different turtles, in order to understand the qualities that sea turtles look for in a nest site and the characteristics that are beneficial to the survival of the hatchlings. Studies have shown that in coarse or dry sand, the turtles will dig several holes termed "body pits," and often emerge onto the beach several nights in a row before they find a spot that fits their "criteria" (Mortimer, 1990). It was found that turtles who nest on beaches with fine-grained sand often emerge only once and make only one egg chamber before depositing their eggs (Mortimer, 1990). These discoveries are most likely linked to the fact that the survivorship of the eggs is lower in dry, coarse sand than it is in fine-grained moist sand (Mortimer, 1990). This finding may also explain why studies have found that turtles are more likely to nest in the monsoon season than in the dry season (Seabrook, 1989). Other studies have shown that sand softness, distance from human settlements, the presence of lagoons, beach length. and beach height are all important factors in the nest site selection of sea turtles (Kikukawa et aI., 1999). The beach height specification is thought to be due to the selection of sites that are high above sea level to keep the eggs from being swallowed by the tide (Kikukawa et aI., 1999).
Life Hi~tory of the Sea Turtle by Brian Clagett Undergraduate Case Western University
July 2002
Sea turtles belong to the families Cheloniidae and Dermochelyidae, of the order Chelonia. These two families are grouped together because of their obvious similarities. They are the only turtles whose forelimbs are more strongly developed than their hind limbs and whose forelimbs have evolved into long paddle-like appendages (Pough, 97). They are also both exclusively marine, and remain in the sea their entire lives, with only the female coming ashore to lay her eggs. The main difference between the Dermochelyidae family and the Cheloniidae is in the arrangement of the shell. The Dermochellds have a leathery skin-covered shell that forms rows that streak down the back, while the Cheloniids have a "typical" Testudlne shell. The family Cheloniidae consists of several species: the Green Turtle (Chelonia mydas). the Black Turtle (Chelonia the Flatback (Natator agassizil) , depressus), the Hawksbill (Eretmochelys imbricata), the Olive Ridley and the Kemp's Ridley (Lepidochelys olivacea and Lepidochelys kempl). There is only one species of Dermochelyidae. the Leatherback (Oermochelys coriacea) (Lutz & Musick, 17-24). All sea turtles share a similar life history. Different
entire lives in the open sea. After hatching, the males migrate to the sea, never to return to land. All seven species of sea turtles share a common life cycle. They migrate from foraging areas to mating areas, and after mating, the males return to the foraging areas while the females return to their native beach to nest (Lutz & Musick, 52). Males and females meet in mating areas which arc not too far from
the nesting areas in order to copulate (Lutz & Musick 58). Very few accounts of sea turtle mating are known, but it is believed that courtship rituals have a greater significance for the females than the males because of the willingness of males to mount objects that are of the "right size and general shape" (Lutz & Musick. 57). The courtship and mating process are believed to be very aggressive. Females come ashore with open sores from bites to the neck, head, and flippers, as well as damage to the shell from the males' claws (Lute & Musick, 57). The aggressiveness of courtship is further evidenced in male
Mirmesota Herpetological Society Monthly Newsletter
The careful selection of the nest site by female sea turtles helps to insure a clutch with high survivorship. This is important for the hatchlings during the first stage of their life, the dispersal to sea. Perhaps the most Important factor in the survivorship of the turtles during this frenzied scamper to the sea is the number of other hatchling sea turtles making the pilgrimage at the same time (Pough, 2001). The turtles are subject to high levels of predation In their unprotected state. That is why the hatchlings work together to dig out of the nest cavity and then wait until nightfall to make their sprint to the sea (Pough, 2001). If the hatchlings dispersed one by one, the predation rate would be much greater.

darkened silhouettes and move towards the horizon (Lutz & Musick, 115). Once the hatchling reaches the sea, it begins to swim. Studies have shown that the turtles will align themselves in respect to the direction of the oceanic waves and swim away fram land (Goff, Salmon, & Lohmann, 1998). Once a turtle reaches deep waters, the contact with the coast is lost, and lost with it is the sensation of the waves. Therefore it is important for the turtles to use some other mechanism of orientation. The sea turtles will then transfer their orienta-
migrations that lead to and from common "meeting" areas, such as feedIng grounds, mating areas, and nesting beaches. Satellite tracking of sea turtles has become very popular in the last two decades. Satellite tracking is accomplished by attaching a clock radio-sized transmitter atop the turtie's carapace. There are four polar orbiting satellites (the same satellites used to monitor weather patterns) that are equipped with Instruments that detect animal tracking transmitters (satintro.htm). Signals sent from the transmitter Include such data as approximate latitude and longitude, number of dives within the last 24 hours, the duration of the most recent dive, the water temperature, and the average speed (satintra.htm). The satellites circle the earth about every 101 minutes and therefore are only over one place on the planet for about 10 minutes. It takes about 3-5 minutes for a transmitter to be detected. Furthennore, the transmitter can only send a signal if it is very close to the surface and therefore It is uncommon to receive a location from a turtle each day (satintro.htm).
The single most important decision a sea turtle must make in its life most likely comes as it emerges from the nest.
The single most important decision a sea turtle must make in its life most likely comes as it emerges from the nest. Sea-finding behavior has been studied in order to find the factors that are responsible for the hatchlings' remarkable seaward journey. The dependence on visual cues for sea-finding has been demonstrated by the fact that hatching sea turtles cannot find the sea when their eyes are covered (Lutz & Musick, 110). It was also found that loggerhead hatchlings orient towards violet, green, and red light, and show an aversion to yellow and yellow-orange light (Witherington, 1991). Studies have also shown that hatchling green turtles are more strongly attracted to blue light than red (Lutz & Musick, 111). The aversion to colors like yellow and yellow-orange may function in preventing the turtles from leaving their nest in the light of day. The preference for shorter wavelengths like blue and green most likely aid in detection of the sea .. Fonn vision was also shown to be important, with studies showing that sea turtles avoid
tion from one induced by waves to one of a magnetic compass (Goff, Salmon, & Lohmann, 1998). A study that placed hatchling turtles in a tank with a wave oscillator surrounded by Helmholtz coils showed that turtles who have swum Into waves for 30 minutes will continue their direction even after the waves have stopped (Goff, Salmon, & Lohmann, I 998) So, the turtles begin their voyages by aligning themselves with waves and then after a short time, make a transition to a magnetic eompass. Once hatchling turtles reach the open sea, they will often remain there for 5 to 20 years during a period coined "the lost years" (Pough, 2001). The "lost years" are still not well understood, but recent evidence indicates that they spend their lives drifting in currents and feeding on food that accumulates in drift lines (Pough, 2001). At some point in their lives, the juveniles must return to the foraging areas and begin their lives as adults. The adult life consists of a cycle of
Satellite transmitters arc often fitted to females as they come ashore to lay their eggs; therefore nearly all of the satellite-tracked turtles are females. Studies of a female green turtle tracked by a satellite show that the foraging grounds for this particular turtle were located over 600 km from the nesting graunds (Papl, et ai., 1995). This turtle followed a slightly curved path to reach its destination and traveled 669 km to the feeding grounds that were 607 km away (straight-path) with an average speed of 2.23 kmlh (Papi, et ai., 1995). In a related study, loggerhead turtles were tracked by satellite and found to migrate fram 545 to 1000 km from
Minnesota Herpetological Society Monthly Newsletter
their nesting grounds to the feeding grounds (Papi, et aI., 1997). Another study utilized a captive-raised loggerhead and found that it migrated a distance of 11,500 km across the Pacific Ocean from Baja California to Sendai Bay, Japan (Nichols, et aI., 2000). The results from this study are surprising, since the animal spent ten years in captivity. The life of a sea turtle seems to be governed by its instinctual behavior. It begins with the synchronous emergence of hatchlings frantically scurrying, empowered by cues of light intensity, color, and form that aid them in their quest to the sea. Then, the rhythmic movements of the ocean's waves guide them on their trek across the vast ocean. Soon they sense the earth's magnetic field and let their internal compass direct them where to go. Years later, they somehow find their way to the group feeding grounds, and later still, to the mating grounds where they will eventually begin to create young that will follow the same journey as their parents.

July Speaker Review by Heather Ingbretson
Hognose Snakes Presented by Curtis M. Eckerman at the MHS General Meeting, July 2002 Hognose snakes are widely known for their infamous death feigning when scared or threatened. They may start by
Ithooding" or flattening out the skin on their head like a cobra and if the threat continues, they will often flip over with their tongue lolling out oftheir mouth and play dead. As if that weren't enough, they will do as much as they can to make them appear as disgusting as possible. They
can emit a rotting smell from their mouths, they can bleed out of their mouths and their cloaca's, they will often
defecate and sometimes even vomit up an old meal. Experienced herpers can attest that they will sometimes flip their head over and smell the air to see ifthe danger has passed and if danger is still present, they will flip back over into their flaccid, death feign again. Although Hognose snakes are probably best known to herpers for this death feign, they are named for their snout which is upturned at the end and is great for digging in the ground. Hognose snakes are most active in the morning and the evening and typically live in loose or sandy soil areas. Curtis discussed the differences between the three types of Hognose Snakes, the Eastern (Heterodon platyrhinos), the Western (Heterodon nasicus) and the Southern (Heterodon simus). The Eastern Hognose is about 0.5 m long and varies in color from totally black to just darker with larger blotches and is found in the Eastern U.S. The Southern Hognose is smaller, about 0.25 m long with the "typical" Hognose pattern. The Western Hognose actually has 3 official subspecies and they can be found

Other research available was conflicting and inconclusive, but most of the evidence
pointed to the Southern and the Western being most closely related. As it turns out, during the Pleistocene, the oceans level receded enough to allow access to the continental shelf near the Gulf of Mexico enough to allow passage of many animals. Normally the passage is blocked by forests and other non-friendly habitats, but the sandy continental shelf floor gave a great habitat with its grassy plains and sandy soils.

The Glacial Lakes Survey

Saturday dawned a little humid but stilI somewhat cool. As animals were most likely to move diurnally, avoiding the midday heat, everyone was asked to arise early in anticipation of a warm day. The survey crew started from camp at about
The second survey of the 2002 season took place in a prairie and oak forested state park in western Mitmesota. Here, we were to trap for turtles, and search for serpents. Our DNR mission was to find Blanding's turtles (Emydoidea blandingii) which are present only one county south. In addition, we were asked to verify undocumented reports of Western Hognosed snakes (Heterodon n. nasicus) in the park. Friday's setup time allowed for only a few observations of frog choruses near camp. These calls MHS herpers head out into the bush .... were comprised of Chorus frogs (Pseudacris I. triseriata) and Cope's Gray Treefrogs (Hyla chlysoscelis). Turtle traps were set while camp was made. Jeff LeClere assisted most ably in the former, having the most trapping experience amongst the group. He also provided a specimen for the Cope's record, and did so while showing his uncanny 'herp-sense' by capturing the hapless frog in one of the turtle traps! After all was prepared, the tired group soon split to their respective shel- ... and return to ters which totaled four tents and two vans to weather a peaceful night. 9:00 AM and began working some of the The night remained cool and breezy short grass prairie nearest to the camp. thanks to a front that had moved through The path for the day would lead from this early in the day.

From the park headquarters, a large loop was made to the best weather of the weekend. south and east canvassing areas near the
western park border eventually returning us full circle. Finds began almost immediately after leaving camp. The first sighting of the day was a Green snake (OphiodlYs vernalis) that eluded capture. This was followed by Prairie skinks (Eumeees s. septentrionalis) Plains, Eastern and Red-sided Garter Snakes (Thamnophis radix, s. sir/alis and sirtalis parietalis). At camp, the traps were emptied; all contained only Painted turtles (Chlysemys piela bellii). After completing the morning round, we took lunch in camp. The intention was to break during the hot midday, but it actually became the end herping of the day. A wind, gentle by morning, soon picked up. Gusting up to 30 mph, it would blow down the authors' tent and the tent of shared food and drink. The temperature steadily rose to an unbearable level even with the wind. On the plus side, other than the ticks, no stinging or biting insects were in any abundance. Some members left to run errands, see relatives, etc. One or two hardier members, more adjusted to the heat continued to search. However, even this attempt seemed futile for several more hours' search turned up only a couple of specimens. One of these proved valuable, however, as it represented a new species to add to our list, Wood frogs (Rona sylvatiea). The rest of the day was spent fighting gear, consuming water and in organization of the campsite and documentation of the finds. Work did not resume on Saturday until nearly ten-o'clock when five members went road cruising for herps. Again, the fruit was meager and yielded calling

Chorus frogs and a few moving Leopard frogs (Rana pipiells). One eager member of the party helped lift everyone's spirit with her enthusiastic drive to capture frogs crossing the road. In fact, the other hapless herpers sitting nearest her soon learned the error of slow response! She soon positioned herself nearest to the door to facilitate a more immediate response
upon the call of 'Frog!' This strategy worked as she soon apprehended her first slippery friend of the evening. The rest watched as she eagerly caught the frog, and caught it, and caught it, finally showing oITher triumph! For those 'old hands' of the field, bored with anything less then a large snake, introducing novices to the fast action found in pursuit of 'mundane'

showed up. Weather probably discouraged some as the forecast was for a rainy weekend, but for those who attended it was still worthwhile to spend time immersed in herps and herping with fellow enthusiasts (personally one of my main reasons for coordinating these). A total of 18 MRS volunteers performed 82 hours of survey time making 38 collection records comprised of ten species. Thirtyseven encounters were either a sighting or a capture, only one was based on an anu-
