Lobsters urinate from their faces
It’s part of the mating ritual
Lobsters wee from their faces. To be precise, they excrete urine from nephropores, or green glands, at the base of their antennae, close to their eyes. Liquid is squirted from a glandular sac that’s connected to the creature’s muscular bladder located under the brain via a coiled tube, and it can be sprayed an incredible seven body lengths ahead of them. They can eliminate waste via their gills, digestive glands and skin too.
As well as flushing toxins from the body, lobsters’ urine is rich in pheromones, which are used for communication, whether warding off rivals or seducing a mate. It’s thought females waft urine into the male’s den to relax him and get him in the mood before entering his home.
