Lobsters have urine nozzles under their eyes, and pee in each other’s faces to communicate.

Lobsters have olfactory sensory neurons, located in the aesthetasc sensilla on their antennules, which allow them to detect the pheromones in the urine of other lobsters.
A dominant male lobster will pee to signal his dominance and deter other males from his territory. Females may also pee to signal their readiness for mating, and the urine of a dominant male can attract females.
Lobsters also communicate through touch and by using their claws, but no one really gives a fuck after reading about the pee thing.
Im interested in the claw communication! How does that work?
Also, the pee stuff is hilarious
Mostly as a show of strength and territorial control. Nothing unexpected. It’s not as nuanced as their pheromone communication.
Ah, so just kinda slappin claws.
I've seen them on the bus I think.
Is there any other way to communicate? Peeing in someone's face is a very effective way to send a message.
