Review of the ecology of sealworm, Pseudoterranova sp (p) (Nematoda: Ascaridoidea) in Icelandic waters
The early life cycle of sealworm in Icelandic waters is not known. Various fish serve as transport hosts but benthic coastal fish, especially bull rout (Myoxocephalus scorpius), probably have a major role in transmission of larvae to the final hosts, seals. Grey seals (Halichoerus grypus) are more h...
