Crab Clueless...

[Captain Michael Buffington]

Definitly a spider crab.......the only time i catch these bastards is in the back water.....so i am guessing it came out of a drum.

But it came from a yellow edge grouper caught at 120 fathoms. That's 720 feet for you liberals.

Looks very similar to a spider crab....but I never recall seeing any red on a spider crab. Mouth looks a little different too....deeper water and lack of light....could be the reason.

edit....and aren't spider crabs supposed to have barnacles on them?

I think I might have a video at work of one that looks similar, much larger however.
Said crab in that video was spotted along a flow-line survey by the ROV. Flow-line on the project is like 36in diameter pipe and according to the guys flying the ROV, it straddled over the pipe with a couple inches to spare all around.
