【分享】魚舌頭寄生蟲

[白鹿 11]

在uglyoverload看到的玩意。

Cymothoa exigua is a parasitic crustacean of the family Cymothoidae. This parasite attaches itself at the base of the tongue of the spotted rose snapper, Lutjanus guttatus, with the claws on its front three pairs of legs, and extracts blood. As the parasite grows, less and less blood is able to reach the tongue, and eventually the organ atrophies from lack of blood. The parasite then replaces the fish's tongue with its own body, by attaching to the muscles of the tongue stub. The fish is able to use the parasite just like a normal tongue, except that it has to share its food with the parasite. It appears that the parasite does not cause any other damage to the host fish

中譯+補充︰白色的東西叫Cymothoa exigua，是一種Cymothoidae屬的寄生甲殼類動物。

這種寄生蟲會抓住肉食性魚的舌頭根部，吸血。當寄生蟲長大壓迫魚舌頭，供應舌頭的血液減少，舌頭就漸漸萎縮壞死。

此時Cymothoa exigua會倒退移動身體，用後足把自己固定在原來控制魚舌頭的肌肉上。這時Cymothoa exigua對魚來說的功能就像原來的魚舌頭一樣，只是當魚掠食，Cymothoa exigua也會分享食物。似乎Cymothoa exigua並不會對魚造成其它傷害。

感謝白鹿...學長提供((一直想叫上司大人= =

恩...其實我覺得舌頭壞死就是一種傷害的樣子....

感覺起來這個舌頭好肥大.不好用

很多的特殊構造就是醬誕生的吧

像葉綠體和粒線體的產生假說

把其他生物"吃"進來共生

也許那種魚在幾萬年之後

就會演化出像異形的那種會吃東西的舌頭

"刷"的一聲飛出來吃掉獵物

(挖!好酷喔~沒想到地球戰場裡的那隻是這樣來的:P)

只是一個是單細胞層次

一個是兩個多細胞個體

不知道有沒有這樣的效果

大腸桿菌不也是一例嗎？

可以幫助合成一些維生素…

也算人體內不可或缺的咧～

我覺得生物應該會趨向於合作吧！
