Summary[edit]

Description
English: Movie 1: Metamorphosis of the pilidium larva of Micrura alaskensis. This time-lapse movie shows a typical sequence of pilidial metamorphosis, in which the juvenile successively breaks through the amniotic membrane and the larval epidermis, then backs out of the larval body while simultaneously consuming the larval tissues. In this sequence, the entire larval body is devoured within a few minutes, and the young nemertean worm crawls away having finished its first meal. The video is sped up 2.5× compared to real time.
