Why is it important?
This study investigates the major claw waving rates and burrow qualities of original- and regenerated-clawed males. The waving rates of original- and regenerated-clawed towards the females are same. Whereas, the quality of breeding burrows of the regenerated-clawed males are better than the burrows of original-clawed males since 80% of the breeding burrows of regenerated-clawed males had breeding chambers but 65% of the breeding burrows of the original-clawed males had breeding chambers. It indicates that mate searching females might get more attracted towards the regenerated-clawed male burrows than towards the original-clawed male burrows for breeding purpose.

Abstract
We studied the effects of claw regeneration on male waving rate and burrow characteristics (i.e., important mate choice criteria) by examining the waving rates and burrow characteristics (diameter, total and horizontal lengths, depth, volume, maximum width, entry and burrow angles, and presence and location of chambers) of large-sized original-clawed males (OCMs) and regenerated-clawed males (RCMs) of Austruca perplexa (H. Milne Edwards, 1852). Female burrows were also examined. The results showed that female burrows were smaller than male burrows, with no chamber and, thus, female burrows are not used for breeding; however, 80% of RCM burrows, and 65% of OCM burrows, had chambers. Other characteristics were not different between RCM and OCM burrows, except for maximum width, which was larger in RCM burrows. The waving rates of OCMs and RCMs were not different. Our results indicate that claw regeneration do not have detrimental effects on male waving rate and burrow characteristics.
