Other Physical Features: ectothermic ; heterothermic ; bilateral symmetry . Lodge. Because of their larger size and more aggressive nature, rusty crayfish can impact fish populations by consuming small fish and fish eggs, and negatively impact fish and spread unwanted aquatic plants by aggressively harvesting underwater plant beds. Competition for refugia in the face of predation risk: a mechanism for species replacement among ecologically similar crayfishes. (2017) found that juveniles from the nonindigenous range have greater plasticity in behavior than juveniles from the native range, resulting in more active juveniles in the nonindigenous range.
