What is the definitive host for Anisakidae?

Explanation:
The definitive host is where the parasite reaches sexual maturity and reproduces. For Anisakidae, the adults live and mate in the stomachs of marine mammals such as seals and whales, so these animals are the definitive hosts. The life cycle includes crustaceans and fish as intermediate hosts carrying larval stages, while humans can become accidental hosts when they ingest infected fish, but the larvae do not mature into adults in humans. Therefore, marine mammals best fit the role of the definitive host for this family.
