Pheromones are chemical ‘smells’ that are released by individuals of aand detected by other members of the same species. Oliver Trottier has proposed that female New Zealand pea crabs release a when they are ready to mate and that male pea crabs follow the ‘scent’ of the pheromone to locate the receptive female within her mussel. In this video, Oliver discusses what pheromones are and describes his ideas about how pea crabs use them.
Oliver Trottier (
A is just a fancy word to say a smell really, sort of a chemical smell that you can pick up on. The situation is that I think the female crab is releasing this pheromone, this scent when she’s ready, when she’s ready to mate, and this sort of prevents the male crab from coming out of his and potentially getting killed for nothing. She sort of lets him know it’s time, I’m ready, I’m going to release this pheromone, and then he can say OK, well I smell, I can smell this, it’s time for me to go.
