We observed pre-copulation behavior of the land snail Satsuma (Luchuhadra) amanoi , an inhabitant of Southern Okinawa Island, in the laboratory. The right individual approached the left one while expanding its gonopore area, which was located at the back of the head. It touched the shell and body of the other, butŽÉ By the way, this species does not have a love dart. The remaining individual shows a hump between the first tentacles, which are said to secrete pheromones. But of what use will it be for this snail once its partner is gone? This video picture was taken 3 days after the filming of ŽÒ Copulation in the land snail, Satsuma (Luchuhadra) amanoi (momo010729sa03b).ŽÓ The individual that approached the other is probably the one that received sperm during the previous copulation. After about a month later, both individuals successfully laid eggs.
