Common look-alikes
- American plaice has a broader, deeper body and a larger, more oblique mouth, lacking the witch flounder's slim, elongated form.
- Yellowtail flounder is shorter and deeper-bodied with rust-colored blotches, whereas witch flounder stays plain and elongated.
- Petrale sole shows a pronounced lateral-line arch that witch flounder lacks, along with a more robust, deeper build overall.
Where you'll see one
Witch flounder inhabit soft mud bottoms in the deep, cold waters of the North Atlantic continental shelf and slope, typically found at depths between 300 and 1,500 feet, well offshore compared to many shallower-dwelling flatfish relatives, and are also sold commercially under the name gray sole.
