The University of Maryland Center for Environmental Science asks the question:
Why Do Oysters Choose to Live Where They Could be Eaten?The answer:
According to an article in the May edition of Ecological Monographs, a team of scientists has found that despite the risk of being eaten by cannibalistic adults, oyster larvae choose to settle in areas of high oyster concentrations to take advantage of future benefits of increased reproductive capacity when they mature.Ohhhh, so, it’s “Why do oysters choose to live where they could be eaten by other oysters? - not by humans.
While I think the latter wording of the question would make for a more interesting experiment, it could not possibly make for a better title of the actual article: “Mechanisms reconciling gregarious larval settlement with adult cannibalism.”
