Pholis gunnellus (Linnaeus, 1758)
The Atlantic butterfish prefers colder waters and can be found among algae, under stones and in rock crevices, on sandy bottoms and muddy substrates. It occurs at depths of 0-100m, but is more often only found at depths of 30m.
Pholis gunnellus has thick fleshy lips and small, conical teeth. A black stripe runs through the eyes. Its dorsal fin is long and has 75-82 spines that start behind the head and extend to the base of the caudal fin.
There are around 12 characteristic black spots on the body, which are bordered by a narrow white band on the sides.
The caudal fin is rounded. The butterfish is yellowish to reddish brown with irregular darker or mottled patterns on the sides of the body.
Pholis gunnellus is said to live to be 5 years old.
Pholis gunnellus is a facultative air breather and can remain out of water for some time under stones or algae. Occurs in shallow waters (coast, tide pools), but descends to 100 m or more (especially in winter).
Feeds on small crustaceans, polychaetes, molluscs and fish eggs.
Its spawn is deposited in large clumps on the seabed and is closely guarded until it hatches. Spawning occurs from November to January. The female lays 80-200 eggs in a large ball under a stone or in an empty mussel shell.
