Cyclops Shark

獨眼鯊魚

This extremely rare cyclops shark, found in Mexico, was confirmed by scientists in October. The 22-inch-long (56-centimeter-long) fetus has a single, functioning eye at the front of its head. The eye is a hallmark of a congenital condition called cyclopia, which occurs in several animal species, including humans.

10月在墨西哥發(fā)現(xiàn)的罕見獨眼鯊魚胎兒。這個胎兒身長22英寸(56厘米)，只有一只眼睛，長在頭部前部。它患有一種名為“獨眼畸形”的先天性疾病，很多動物都會出現(xiàn)獨眼畸形，包括人類在內(nèi)。

Scientists have documented cyclops-shark embryos a few times before, said Jim Gelsleichter, a shark biologist at the University of North Florida in Jacksonville. The fact that none have been caught outside the womb suggests cyclops sharks don't survive long in the wild.

杰克遜維爾北佛羅里達州大學研究鯊魚的生物學家吉姆·格爾雷切特表示，科學家此前就曾多次發(fā)現(xiàn)獨眼鯊魚胎兒。但他們一直未能在母體外捕獲獨眼鯊魚，說明這種鯊魚無法在野外存活很久。
