Paper on the relation between crab burrows and cometary pits was published in Sci. Rep.

This study reveals a peculiar relation between sandy crabs and comets by a simple wet granular experiment. In the experiment, a horizontal tunnel in a wet granular layer was compressed. Then, the shrink or collapse was observed depending on the initial size of the tunnel. This phenomenon could relate to the stability of crab burrows and size of pits found on comets.
