The ecological group for each species is shown in parentheses after the host name. Ecological groups mainly assigned following Koen-Alonso et al. [62] and Romero et al. [63]. The 95% C.I. were only estimated for fish species with n ≥ 15. Abbreviations: B benthic, DB demersal–benthic, DP demersal–pelagic, Li liver, Me mesenteries, Mu muscles, P pelagic.
*Sealworms molecularly identified as Pseudoterranova cattani George-Nascimento & Urrutia, 2000 (n = 3; except P. isosceles, n = 1).
