Grosser Than Gross

I know many useless bits of information. Many of the things I know, other people tend to find somewhat disgusting. People say, "How do you know these things?", and I just say, "I really don't know.". I guess my brain is just attuned to noticing odd, disgusting, or strange things. Like how I just found this today. Enjoy.

(Note: How do these parasites reproduce? Is there some sort of underwater fishy french kissing thing going on that we don't know about? *shudder*)
