PERRYVILLE, Mo. – Missouri Department of Conservation (MDC) biologists are documenting reproduction of the endangered grotto sculpin in Perry County caves. The grotto sculpin is a small cave fish that is only found in Perry County. It is also unique because the species seems to be currently evolving. They have varying levels of pigment, and some have eyes while others don’t, as the species adapts to cave conditions. MDC has researched the rare fish for well over a decade, but the current research project is focused on assessing population numbers and status, which includes reproduction.
