The cunner (Tautogolabrus adspersus), also known as the blue perch, bergall, chogset, choggie,[2] conner or sea perch,[3] is a species of wrasse native to the northwestern Atlantic, where it is found from the Gulf of St. Lawrence and Newfoundland to the Chesapeake Bay.

They inhabit inshore waters living near the sea floor at depths from 10 to 128 m (33 to 420 ft), preferring areas with beds of seaweed, shipwrecks, or wharf pilings.

Cunners are generally smaller, so are usually thrown back by anglers who think they caught a "short" tautog.

They can be confused with black sea bass, rockfish and other grouper, as well as tautog, for their ability to change color.

Cunner can enter a hypometabolic state in response to cold temperatures and hypoxic conditions.
