Holes on the Ocean Floor, origin unknown. Scientists asking public for thoughts

That's pretty intriguing to look at.

The proportion of the holes (longer than wide) and irregular spacing caught my eye.

Just for fun I'd guess it's a predatory pattern in which a creature dives under the sand (first small crater hole at bottom of the photo) burrows for a bit, and then emerges to capture prey, then reenters the same hole, burrows for a bit to where there's not such an obvious disturbance in the surface, and repeats the hunt.

The comparatively wide dispersal around the holes could be a sign of a high-velocity leap...

A straight line huh? Seems to imply that they're created by one creature. Is it something that crawls over the ocean, making the holes? Or is it something in the sediment that pokes holes upward? Again, the straightness of the line makes you think it's the latter.
