Lumpfish
Cyclopterus lumpus
Key differences: Lumpfish have a stout, globular body, prominent bony tubercles, and a suction disc formed by modified pelvic fins. Eelpouts are elongated and lack these features.
Butterfish
Pholis gunnellus
Key differences: Butterfish (or Gunnels) are also elongated but typically smaller, have a row of distinct black spots along the dorsal fin base, and their dorsal and anal fins are not as extensively confluent with the caudal fin as in the Eelpout. Their pelvic fins are also much smaller or absent.
Other Eelpouts (Zoarcidae)
Various species
Key differences: Distinguishing Zoarces viviparus from other Zoarcidae species often requires careful examination of fin ray counts, vertebral counts, and specific head morphology. Z. viviparus is generally characterized by its specific range of dorsal (70-85) and anal (55-70) fin rays and its viviparous reproduction.
