horseshoe crabs’ blood

Horseshoe crab

馬蹄蟹於四億年前已存活在地球上,是標準的活化石。牠們的藍色血液可製成測試劑,一直被用作檢驗活菌和細菌內的毒。馬蹄蟹的繁殖率低,而美國每年有三萬隻死於實驗,令牠們受到威脅。現今不少國家已認可用人血做試驗,無需再危害馬蹄蟹。

horseshoe crabs have been on earth for over 450 million years, and are often called living fossils. their blood is blue and are used for testing bacterial contamination. the reproduction rate of horseshoe crabs are low, and they are endangered. however, over 30 thousands of crabs are killed furring or after the blood harvest process. more and more countries recognized using human blood for testing, and could reduce causing more harm to the horseshoes crabs.
