Bivalves don't have an enclosed circulatory system like ours. Instead their body fluid (called hemolymph) is circulated around their body cavity by their heart, including blood cells called hemocytes. Some hemocytes work much like our white blood cells, engulfing pathogens (190)

This project started when shellfish biologists at the Squamish Tribe teamed up with PSRF to start a hatchery to increase the numbers of basket cockles in the area. One first step was a health screen, where they found disseminated neoplasia, a cancer mostly found in hemolymph.

no, this is much worse. best case scenario is you're "just" killing off hemocytes, but you could also be creating carcinogens in the process
