The Bear Lake Sculpin is a small, benthic fish characterized by its broad, flattened head, mottled brown and gray coloration, and large pectoral fins adapted for maneuvering along rocky lake substrates. Endemic to Bear Lake, it is an essential component of the lake’s food web, preying on invertebrates and serving as prey for larger fish. The sculpin’s adaptations to deep, cold, and oxygen-rich waters highlight its unique evolutionary niche.
