How to tell them apart

Northern Stargazer

Buried head-up in the sand: eyes and a fringed mouth on TOP of a blunt head, white-spotted black body — and an electric organ behind the eyes, so use pliers.

Oyster Toadfish

Camouflaged grumpy blob with a huge mouth; croaks.

Oyster toadfish, next to northern stargazer: mouth on the front of the face, not the top.
