Lysmata wurdemanni is a reef safe cleaning animal which consumes parasites and dead or diseased tissue from other animals, and is therefore used in marine aquariums. This process is very brief and occurs immediately post-moult, while the female's cuticle is new and soft. If the chemicals are right, courtship may commence and, if courtship goes well, copulation will ensue. The male will then 'taste' the female's contact pheromones with his aesthetascs to make sure she is a suitable mate. Guided by these chemical signals, males make their way to the female and will approach her. ![]() These pheromones are released 2–8 hours prior to female moulting. Males use olfactory organs (aesthetascs) on their antennules to detect soluble female sex pheromones (distance pheromones). Lysmata wurdemanni employs a 'pure searching' tactic for mate-finding in which the males are constantly searching for receptive females. During this hermaphroditic stage the shrimp gradually lose their male organs, likely because more energy is being allocated to the development of female reproductive organs. In the euhermaphrodite stage the shrimp act as a male between moults and as a female immediately following a moult. However, under certain conditions some males never change to hermaphrodites. It has four moults as a male before changing sexes to become a euhermaphrodite. This means that it begins as a male but may later become a hermaphrodite. Lysmata wurdemanni is a protandric simultaneous hermaphrodite. ![]()
