I just looked it up—it injects itself into the crab's body and replaces the crab's genitals with itself, grows roots into the crab's organs (including its brain), and controls the crab's behaviors so the crab will take care of the Sacculina larvae as a female crab would its own babies—if the crab is male, the Sacculina parasite will make the crab's body produce female hormones to basically change it to female.

as long as you smile and nod, people are satisfied. it’s just to show that you are nice and there with good intentions. we’re small in a big world and have to rely on other people to be decent to us. so we do our little human dance to each other to say, “i’m not here to hurt you. here’s something we have in common, like the weather or sports or itchy sweaters, so we both know we’re on the same team. we both agree on a basic fact, like that it is rainy or that being itchy is uncomfortable, and this proves we can get along. i’m being light-hearted and non-threatening right now.”

small talk isn’t to get to know a person. it’s just a greeting to affirm you’re buddies in the universe.
