鱷魚:處淤泥而不染,全靠免疫強悍

Specifically their immune system.

尤其是它們的免疫系統。

Crocodiles immune system is so strong that human bacteria literally explodes on contact with crocodile blood.

鱷魚的免疫系統是如此強大,以至於人體的細菌一接觸到鱷魚的血液就會爆炸。

No wonder they have changed so little over the course of their evolution.

這也就不難理解,為什麼在漫長的進化過程中,鱷魚的改變卻如此之少。

鱷魚:處淤泥而不染,全靠免疫強悍

Professor Britton: “The crocodile has an immune system which attaches to bacteria and tears it apart and it explodes. It’s like putting a gun to the head of the bacteria and pulling the trigger”

布里頓教授說:“鱷魚有一個強大的免疫系統,它能夠附著在細菌上,把它們撕裂並炸開。就像是用槍瞄準了細菌頭部,然後扣動了扳機。”

鱷魚:處淤泥而不染,全靠免疫強悍

(鱷魚在激烈的領土爭奪戰中會遭受重傷,不僅如此,它的居住環境也充滿細菌。儘管傷口會感染細菌、病毒和真菌,但依然能很快癒合。它的免疫系統能抵抗以前沒有出現過的真菌、病毒和細菌等微生物。)
