===Reproduction===
Sexual reproduction occurs once the larvae have reached a definitive host and completed their final molt, at which point sexual organs are developed.<ref name="Ángeles-Hernández">{{cite journal |last1=Ángeles-Hernández |first1=Juan C. |last2=Gómez-de Anda |first2=Fabian R. |last3=Reyes-Rodríguez |first3=Nydia E. |last4=Vega-Sánchez |first4=Vicente |last5=García-Reyna |first5=Patricia B. |last6=Campos-Montiel |first6=Rafael G. |last7=Calderón-Apodaca |first7=Norma L. |last8=Salgado-Miranda |first8=Celene |last9=Zepeda-Velázquez |first9=Andrea P. |title=Genera and Species of the Anisakidae Family and Their Geographical Distribution |journal=Animals |date=2020 |volume=10 |issue=12 |pages=2374 |doi=10.3390/ani10122374|pmid=33322260 |pmc=7763134 |doi-access=free }}</ref> Females are capable of producing 2.6 million eggs, depending on species and size at sexual maturity.<ref>{{cite journal|last1=Ugland|first1=Karl Inne|last2=Strømnes|first2=Einar|last3=Berland|first3=Bjørn|last4=Aspholm|first4=Paul Eric|date=1 April 2004|title=Growth, fecundity and sex ratio of adult whaleworm ( Anisakis simplex; Nematoda, Ascaridoidea, Anisakidae) in three whale species from the North-East Atlantic|journal=Parasitology Research|volume=92|issue=6|pages=484–489|doi=10.1007/s00436-003-1065-5|pmid=14999465|s2cid=7128855}}</ref>
