BULLHEAD

The shape of this odd little fish has deserved it the additional name of "Miller's Thumb": it has a large head with wide spiky gill-covers - wide pectoral fins - a small tapering body - scaleless skin blotched with brown and yellow - and two dorsal fins close together - with dark stripes. It is widespread in British waters - especially in clear streams - where it stays on the bottom - darting occasionally to swallow any creature small enough to enter its capacious mouth. The average length is about 3 or 4 inches - occasionally up to 6 inches.
