六斑刺魨，學名：Diodon holocanthu為輻鰭魚綱魨形目二齒魨科的一種，俗名刺乖、刺龜-體長可達50公分。
本魚分布全球各大洋亞熱帶海域，棲息於礫石底質區域，游速慢，遇攻擊時會吸入大量海水將身體鼓脹成圓球狀，並豎起棘刺。屬肉食性，以底棲動物為食。春末夏初的繁殖期會大量聚集。
近期在漁港作釣常魚到大量的刺龜在搶食你的魚餌，魚餌跟本還沒到魚的嘴就被吃光了，怎麼這麼多啊！，原來...有人在放生刺龜，價格低廉的刺龜近期變成放生當紅的魚種...花少的錢就可放生量大的魚，或許滿足了他們的願望。
有需求就有人會供貨，這是一個供需的循環。之前新聞也有報導：最多一次放生2500隻，在這需求下刺龜的
價格也從 5塊變10塊,或許給當地小孩賺點小外快，但放生後滿海的刺龜卻也苦了釣魚人..........

Fugu (河豚 or 鰒; フグ) is the Japanese word for pufferfish and the dish prepared from it, normally species of genus Takifugu, Lagocephalus, or Sphoeroides, or porcupinefish of the genus Diodon. Fugu can be lethally poisonous due to its tetrodotoxin; therefore, it must be carefully prepared to remove toxic parts and to avoid contaminating the meat.

The restaurant preparation of fugu is strictly controlled by law in Japan and several other countries, and only chefs who have qualified after three or more years of rigorous training are allowed to prepare the fish. Domestic preparation occasionally leads to accidental death.

Fugu is served as sashimi and chirinabe. Some consider the liver to be the tastiest part, but it is also the most poisonous, and serving this organ in restaurants was banned in Japan in 1984. Fugu has become one of the most celebrated and notorious dishes in Japanese cuisine.
