Cusk

Cusk are solitary cod relatives that prefer cold, clear Norwegian waters and are common on the rocky slopes at Munkholmen below 10 m. They lodge themselves in crevices during the day, their single continuous dorsal fin giving them an eel-like profile. Cusk are long-lived and slow-growing, making undisturbed sites like Munkholmen particularly important for sustaining local populations.
