        <RULE_TITLE>Endangered and Threatened Wildlife and Plants; Listing Determination and Critical Habitat Designation for the Grotto Sculpin</RULE_TITLE>
        <ABSTRACT><![CDATA[We will make a listing determination and designate critical habitat for the grotto sculpin (Cottus spp.) pursuant to the Endangered Species Act. The sculpin, a cave-dwelling fish, is restricted to two karst areas (limestone regions characterized by sink holes, abrupt ridges, caves, and underground streams), the Central Perryville Karst and Mystery-Rimstone Karst, in Perry County, southeast Missouri. The current overall range of the grotto sculpin has been estimated to encompass approximately 260 square kilometers (100 square miles). The small population size and endemism of the grotto sculpin make it vulnerable to extinction due to genetic drift, inbreeding depression, and random or chance changes to the environment. Current threats to the habitat of the grotto sculpin may exacerbate potential problems associated with its low population numbers and increase the likelihood of extinction.]]></ABSTRACT>
