    Restoration project aims to help king crab recover from near extinction in Taiwan (2021/10/13)

    The king crab is a "living fossil," having been on Earth 400 million years. But in the last decade, it's been driven to near extinction in Taiwan. This year, reports say only six adult king crabs were caught in the wild. Now the National Museum of Marine Science and Technology is working with officials from Kinmen County on a restoration project. They hope to help the crab reproduce in captivity, so they don't go extinct.

    A king crab crawls along the aquarium floor like a tiny living tank. Its hard shell is so tough, few would imagine how soft and vulnerable it is as a baby.

    These tiny creatures are the young crabs, rolling around inside their translucent eggs. A sea of eggs sits on a bed of broken shells. The yet-to-hatch babies look odd but adorable, like mini jellyfish.

    This is the first time I've seen a king crab so close up, for sure. I think it's amazing. How can these things have been around for so long?

    The king crab species has been on Earth for over 400 million years. Now in Taiwan's waters, it faces extinction, which is why the National Museum of Marine Science and Technology has stepped up.

    Right now we've reached the stage where we can carry out successful artificial breeding programs, and increase the number of larvae. We're looking forward to raising them up a bit bigger so we can restore the population.

    The museum is working with Kinmen County Marine Products Research Institute on the project. They've also got local university students involved. King crab is sometimes called "living fossils," because the species has barely changed for hundreds of millions of years.

    The king crab's blood is extremely sensitive to microbes and to a number of toxins. We can use it to detect toxic reactions to vaccines and other drugs - it's so useful and sensitive.

    Keelung was once home to a large population of king crabs. But as its ocean habitat has been destroyed, it's been driven to near extinction in Taiwan. Scientists hope their restoration efforts will help this living fossil keep on living one more generation.

    "活化石"鱟面臨生存危機海科館著手進行復育

    存在地球有四億多年的鱟,有"活化石"之稱的鱟,過去在基隆曾有大量鱟族群繁衍,如今受到棲地影響,數量大減,今年收購野生的成鱟,僅僅剩下6尾,基隆海科館展開復育計畫,與金門水試所合作,讓這珍貴的海洋生物,繼續存在地球上。

    鱟在水底爬行,看上去像是在海洋世界的小坦克,硬梆梆的剛毅形象,讓人無法想像,還沒孵化的鱟寶寶,長得很不一樣。

    一顆顆晶瑩剔透、圓滾滾的半透明小球,堆疊在碎貝殼上,裡頭還有不停翻滾、還沒孵化的寶寶,模樣古怪又可愛,還有點像水母。

    [[遊客]]
    “真的第一次這麼近的看到鱟,然後就覺得,好神奇哦,這種東西怎麼可以活這麼久。”

    鱟這個生物已經在地球四億多年了,現在在台灣面臨生存危機,海科館著手進行復育。

    “目前我們推進到,我們能夠很成功地在做人工繁殖,把牠的幼苗的數量擴大,然後我們就期望說,我們能夠養到稍微大一點,再去做復育。”

    基隆海科館與金門水試所合作,還深入校園,讓學生參與鱟卵的孵化。而鱟之所以稱作"活化石",就是因為從過去到現在,都保留原來的模樣。

    “鱟的血對於細菌,還有一些毒素的敏感度非常地高,還有一些比如說疫苗啦、藥物的毒素反應,用牠來做偵測是非常好用且靈敏的。”

    過去在基隆曾有大量鱟族群繁衍,但隨著沿岸棲地的消失,如今幾乎從台灣本島絕跡,希望透過復育計畫,讓這活化石別消失在地球上。
