s. Throughout its range in California, these snails grow and reproduce from spring through fall (March–October) and cease growth and reproduction during the winter (November–February). Maximum longevity for these snails is at least 6–10 years, and this appears to be the case for uninfected as well as infected snails. At least 18

species parasitically castrate California horn snails. A trematode infects a snail with a miracidium larva that either swims to infect the snail, or hatches after the snail ingests the trematode egg. After infection, the trematode parthenitae clonally replicate and produce free-swimming offspring ( cercariae). These offspring infect second intermediate hosts (various invertebrates and fishes) where they form cysts (metacercariae). The trematodes infect bird final hosts when birds eat second intermediate hosts. Ceredithidea californica Morro Bay CA
