有情況甚至是頭部與心臟、大腸、性器官等分離。而其脫離的頭部則吃著海藻維生。602Please respect copyright.ＰＥＮＡＮＡptzfC82NlN

7日後，頭部發展出心臟等器官。約20日後，所有器官亦能順利發展成為原狀，又一條好漢。602Please respect copyright.ＰＥＮＡＮＡ9g08URbhkZ

（圖3）自然情況下，當海蛞蝓遭受到寄生蟲入侵時，進行自割並頭身分離的情況亦會發生。602Please respect copyright.ＰＥＮＡＮＡmFkkxSTloq

鑑於這情況的發生，有理由可相信海蛞蝓進行自割是天生用來對抗外敵入侵的手段。602Please respect copyright.ＰＥＮＡＮＡFII5iSBxIr
