<br />A. Descri Dt ion <br /> <br />The Kanab ambersnail is a terrestrial snail in the family Succineidae. The <br />empty shell is a light amber color. The live snail has a mottled grayish- <br />amber to yellowish-amber colored shell. The shell is dextral (right handed <br />spiral). thin-walled. with an elevated spire and a broad. patulous (expanded) <br />aperture. Fully mature individuals are about 14 to 19 mm (0.5 to 0.75 inch) <br />long, 7 to 9 mm (0.25 to 0.33 inch) in diameter, with 3.25 to 3.75 whorls in a <br />drawn out spire. Its eyes are borne at the ends of long peduncles (stalks), <br />. while the tentacles are reduced to small protuberances at the base of the eye <br />stalks (Pilsbry 1948. Clarke 1991). <br /> <br />B. Distribution <br /> <br />The Kanab ambersnail is currently known from three populations (Figure 2). <br />The majority of the species total known population is located at Three Lakes <br />about 10 kilometers (six miles) NNW of Kanab in Kane County. Utah (Clarke <br />1991). This population inhabits wet meadow and marsh habitat (approximately <br />0.8 kilometers [0.5 miles] long) surrounding the "Three Lakes" ponds. A <br />second population is located in Kanab Creek Canyon 10 kilometers (six miles) <br />north of Kanab, also in Kane County (Clarke 1991). This population exists in <br />a marsh about 46 meters Q150 feet) long and 15 centimeters (6 inches) wide <br />adjacent to the main stem of Kanab Creek. The two Utah populations are about <br />2.1 kilometers (1.3 miles) apart near the Utah-Arizona border. The third <br />population is located at Vaseys Paradise along the Colorado River in the Grand <br />Canyon in Coconino County. Arizona. about 52 river kilometers (32 river miles) <br /> <br />3 <br />
