（圖2）有科學家嘗試用尼龍蠅綁住海蛞蝓(Sea Slug)的頸部，發現牠們有能力進行自割，頭身分離。500Please respect copyright.ＰＥＮＡＮＡoP6ylKDWFX

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。500Please respect copyright.ＰＥＮＡＮＡCIoOaOBWXj

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。500Please respect copyright.ＰＥＮＡＮＡzEvWBv4JSU

（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。500Please respect copyright.ＰＥＮＡＮＡq0COECRAyK

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。500Please respect copyright.ＰＥＮＡＮＡIwFLBQJFSS

此地不宜久留之時，若有逃生門手段可走，自然界的生物自當會不惜一切進行逃離。500Please respect copyright.ＰＥＮＡＮＡlvBvruC4rO
