Porn Base Flatworm reproduction asexual reproduction Close Freshwater planarians, found around the world and commonly known as "flatworms," are famous for their regenerative prowess. Through a process called "fission," planarians can reproduce asexually by simply tearing themselves into two pieces -- a head and a tail -- which then go on to form two new worms within about a week. When, where and how this process unfolds has remained a puzzle for centuries due to the difficulty of studying fission. Planarians are notoriously difficult to study. They do not like to be watched during fission, which primarily happens in the dark and halts at the slightest disturbance. Because fission does not happen frequently -- approximately once a month for certain species -- continuous video recordings are required to capture planarians in the act to study the details of its regeneration. To understand where and how fission occurs in the planarian species Dugesia japonica , the researchers employed a mix of time-lapse video recordings, sensitive traction measurements, statistical analysis of hundreds of divisions and mathematical modelling.
