Sorry, no etymologies found.
Actually more of a barnacle with a parasitic bent, the sacculina starts out life as a weensy, free-floating organism, swimming about the seas.
Although she spends her early life footloose and fancy-free, what the female sacculina really wants is to meet a nice crab and settle down.
You (hopefully) can't inject the gooey center of yourself into your neighbor and take over his brain, but you can take the story of the sacculina as a parable showing you how mooching should be done.
