Clearnose skate. We worked on these guys last year determining how quickly they digest their food. The "old" estimate was a much slower rate of digestion.

The group photo is/are clearnose skates
The single photo is of a "pigment impaired" Winter skate.
The difference??
Not so much the appearance as the maximum size and a small rough patch on the underside of the fish...
What you may find in the restaurant could likely be the Winter Skate.
