| Outline of Final Research Achievements |
Ghost crabs make cm-scale-diameter burrows on appropriately wet sandy substrate. Physically, such a sandy substrate can be regarded as wet granular matter. Thus, the size and distribution of crab burrows might be governed by the stability of a void structure in wet granular layer. In this study, we performed the experiment and field work to quantitatively reveal the relation among the mechanical properties of tunnel structure in wet granular layer , spatial distribution of crab burrows, and their size distribution. From the obtained results, we found that the actual crab burrows are sufficiently stable in terms of wet granular mechanics.
