However, none of the pea crabs from the larger clams were infested with hyperparasitic isopods, whereas all five pea crabs from the smaller clams were infested with hyperparasitic isopods (significantly different from a predicted equal distribution: p <0.001 Fisher Exact Probability Test). The larger and smaller clams were from the same clutch (i.e., same age). We cannot definitely state the pea crabs from the 2013 collection were infested with
