Orconectes rusticus is also less susceptible to predation than resident crayfishes
due to larger chelae (Roth and Kitchell, 2005).
Although this study lacks the scope to fully address this issue, the distribution and habitat preferences of the crayfishes
of Blackburn Fork appear to vary widely and reflect the diverse range of niches occupied by different species.
