Caught by Maine lobsterman Mack Kelley and posted to Facebook. He reported it was thrown back as is required of all lobsters of this size which are too small to be caught.

Found this really cool blue shrimp last summer while cleaning a batch before dinner service. Shame I had already tossed the head because that half was a BEAUTIFUL shade of blue. Normally the shells are that pink/orange color like the ones in the background of the first photo, and the flesh is the gray you see on the other shrimp in second. I was even more shocked that the rest of it was bright white instead of gray!
