Anisakidae (Anisakis simplex, Pseudoterranova decipiens, Hysterothylacium, etc.)
Herring worm; Whale worm
Highly abundant genus of ascaridoid roundworms ( Nematodes; Figs. 1–3, pp. 87, 88) of the family Anisakidae. The parasites are associated with aquatic organisms and can be found in a variety of marine hosts including whales, crustaceans, fish, and cephalopods.
The general life cycle (Anisakidae) of these parasites involves broad range invertebrates such as crustaceans and chaetognaths, teleost fish species, and cephalopods, which act as intermediate and/or paratenic hosts. Marine mammals (toothed and baleen whales, sometimes seals) serve as definitive hosts. Toothed and baleen whales of the families Delphinidae, Ziphiidae, Physeteridae, and Kogiidae are considered the main definitive hosts, but members of Balaenopteridae, Pontoporiidae, Monodontidae, Phocoenidae, and Neobalaenidae have also been documented. Adult Anisakislive in the alimentary tract of their definitive hosts where they reproduce. The eggs are dispersed...
