Ecology

''Cerithideopsis californica'' lives in salt-marsh dominated estuaries. The snails primarily feed on benthic diatoms. 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

trematode Trematoda is a class of flatworms known as flukes. They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, is usually a snail. The definitive h ...
