Clamming down

Noticed possible Nematoda in my clams for dinner. They were about 3cm in length,translucent, and symetrical to each end.Trying to recall my phylogeny, I assumed most marine-based ones are also parasitic.I couldn't detect the presence of a mouth, so perhaps my hypothesis was inncorrect. Not having an objective lens nearby didn't help matters. I contemplated keeping the specimens for further investigation at work, but instead threw them out, and continued eating the clams, hoping that any potential larvae were killed off by the steam from cooking. My physical hunger overrode any potential intellectual gains this night. Silly me.
