Red Drum
Sciaenops ocellatus · also called redfish, channel bass
In a shallow Gulf Coast estuary, a red drum tips forward to root along the bottom for a buried crab, the dark eyespot near its tail catching a predator’s attention just long enough to buy the real head a crucial head start.
Overview
The red drum, Sciaenops ocellatus, widely known as redfish, is a coppery-coloured coastal fish native to estuarine and nearshore waters along the Atlantic and Gulf coasts of North America. Its distinctive tail eyespot and unusual ability to drum sound from its own swim bladder make it one of the more behaviourally and physically distinctive fish found in southern coastal waters.
A decoy built right into the body
Rather than relying purely on speed or camouflage, the red drum carries a built-in trick near its tail, a false eyespot that can turn a predator’s strike into a survivable graze instead of a fatal hit to the head.
Status
Least Concern — widespread and stable across suitable coastal and estuarine habitat along the Atlantic and Gulf coasts, supported by fishing regulations introduced after historical overfishing concerns.
Red Drum: common questions
Why does the red drum have a spot near its tail?
A red drum typically displays one or more black, eye-like spots near the base of the tail, a marking thought to help confuse predators into striking the tail end of the fish rather than the more vulnerable head, giving the red drum a better chance of escaping with only minor damage.
How does a red drum make a drumming sound?
A male red drum produces a deep drumming or croaking sound by vibrating specialised muscles against its swim bladder, a behaviour that becomes especially common during the breeding season and is thought to play a role in attracting mates.
Is redfish the same thing as red drum?
Yes, the red drum is widely known by the alternate common names redfish and channel bass, particularly among recreational anglers along the Gulf and Atlantic coasts, and all three names refer to the exact same species.
Where does the red drum live?
The red drum is native to coastal and estuarine waters along the Atlantic coast from the mid-Atlantic United States south through the Gulf of Mexico, typically spending its early life in shallow estuaries before larger adults move into deeper nearshore water.
