Feeding selectivity of slimy sculpin Cottus cognatus and deepwater sculpin Myoxocephalus thompsonii in southeast Lake Michigan: Implications for species coexistence

► Slimy and deepwater sculpin select different prey types and sizes, which may contribute directly or indirectly to species coexistence ► Variation in sculpin prey-type selection probably contributes to widely reported differences in the diet composition and bathymetric distributions of the two species ► Declines in Diporeia abundance did not appear to impact sculpin food resource partitioning, at least as of 2002.
