Caption
The life cycle of an Anisakis worm. The worms reproduce in the intestines of marine mammals and are released into the ocean via their feces. After the worms hatch in the water, they first infect small crustaceans such as krill. When small fish eat the infected crustaceans, the worms then transfer to their bodies, and this continues as larger fish eat smaller infected fish. Humans and marine mammals can become infected when they eat a fish that contains the worms.
