Crabs court their perspective mates by building them a “temple,” whilst male fishes build their “nest”. Both are used to attract females and acts as substrates for hatching/laying of eggs.  You'd think their odd body shape and rigid shells would make mating physically difficult. So just how do crabs do it? In order to grow and increase their size, crabs must first molt, or  shed their exoskeleton . And it is only during this molting period — when the new shell hasn't yet hardened — that most aquatic crab species mate.  Like most fishes, crabs do release pheromones too, however, varying on what specie of crab it is. For some specie like blue crab (Callinectes sapidus) , the males release pheromones then use their claws to fan the scent towards prospect females. But in some species including Dungeness crab (Canc...
