Diverse and extensive macrofouling of the left‐hand (eyed) side has been observed in multiple films and photographs of different specimens of Eckström's topknot Zeugopterus regius . Identified foulers include macroalgae and tunicates. Photographs of unfouled specimens and preserved juveniles have also been inspected. Macrofouling is not universal in this species; unfouled fish were observed around the strongly tidal British Isles, whereas the worst‐fouled topknots were seen in the eutrophic, microtidal northern Adriatic.
