Roanoke logperch
The Roanoke logperch (''Percina rex'') is a small freshwater fish found in the Roanoke and Chowan drainages in Virginia, United States. They inhabit low and moderate-gradient streams and rivers in warm, clear water in mostly unsilted gravel and rubble in runs, pools, and riffles. They are primarily insectivorous. This fish is a federally listed endangered species.
==Description==
Adults of these fish are between 80 to 115 mm SL. The light-colored body is somewhat stocky and elongate. There are dark, rounded, and vertically elongate blotches on the side. They have a long, cone-shaped snout with a bulbous or blunt tip. There are two dorsal fins, which are both very tall on adult males; the first dorsal fin has an orange band bordered on both sides by black bands. The end of the tail fin is almost straight. The fins have black or brown dark marks on them. The large eyes are near the top of the head of the fish. The fish's upper jaw is longer than its lower jaw.
