This is cool, the “holes” look very uniform in size and shape. Curious if there is any other evidence of these formations arranged in a non-linear way

They also look very recent. The sand hasn't filled them back in.

I don't think there's much water movement that deep, so they may not fill back in like we'd expect. I think there's almost no current down that far, and marine life that would knock them over are scarce.

I used to work with deep sea ROVs. We also found geometric hole patterns in rocks. Much smaller than these. It's truly weird to find.

Remnants of ripped up subsea Chinese listening devices ?
