When gammarus shrimps are attacked by a parasitic worm, the parasite is visible from the outside as a red/orange dot. Thanks to this hot spot, fish not only see it better, but also find it more attractive! Only fish that are suitable as hosts, (trout) preferentially eat the infected shrimps.Thereafter the parasitic worm completes its development in the fish. . Need I say more?
