Butterfish
Pholis gunnellus
Sighting evidence at Munkholmen Island, Trondheim Fjord
Butterfish are small intertidal eelblennies common in the shallow boulder zone at Munkholmen, identifiable by the row of white-ringed black spots along their dorsal fin. They shelter under stones and in kelp holdfasts, emerging to forage on amphipods and small invertebrates. Males guard egg masses attached to rocks during winter, making them approachable for macro photography in calm conditions.
