過一段時間後，器官便會再生回復至原來的樣貌，其體積有機會比原來的更為細少。552Please respect copyright.ＰＥＮＡＮＡkbKMnR9yj0

（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。552Please respect copyright.ＰＥＮＡＮＡjIkTm3uBUL

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。552Please respect copyright.ＰＥＮＡＮＡe9BECm4Xia

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。552Please respect copyright.ＰＥＮＡＮＡhHMRan2c7K

至於被遺棄的身體，則隨著時間變得暗淡及萎縮，沒能長出頭部。552Please respect copyright.ＰＥＮＡＮＡabdzPyOUHL

（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。552Please respect copyright.ＰＥＮＡＮＡnm0hKdCNpf

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。552Please respect copyright.ＰＥＮＡＮＡINdxul5BVI

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。552Please respect copyright.ＰＥＮＡＮＡmn5OQCpShi
