• The apodid sea cucumber Polycheira fusca that was pushed hard on its body surface ejected the wart contents including the wheel-shaped ossicles from the body wall. The ejection always occurred quickly in a small circular region around the press point, indicating that pushing caused a nervous signal, which was diffusely conducted to the surrounding area and induced rupture of the warts and ejection of their contents. All ejected ossicles dispersed but were still attached to the wall by a branched string connecting the ossicles to the wall. The selective advantage of ejecting the wart contents was discussed.
