On the South Australian island, the BBC's famous filmmakers found hundreds of blind snakes and head injuries. Is this the characteristic of the 'residents' on this desert island or do they have some strange syndrome?

Sir David Attenborough, an English naturalist, author of the documentary series "Life in cold Blood" has found the answer to the strange phenomenon of cobra snakes on this uninhabited island.

Tiger Snake is a poisonous snake that ranks third in the list of "Top 10 most dangerous snakes in Australia" voted by Australiangeographic. This snake possesses a colorful appearance and powerful nerve venom.

But, the cobra is not the "king" of this island, it is also the 'home' of one of their strongest enemies, the silver gulls. The cobra always tries to find a way to kill this enemy but they encounter a strong gull protest. With high legs, strong hard beaks and wings, gulls are ready to use the "pounding" dozens of hits on the snake's head when they see them approaching.

And this is the cause of the BBC film crew seeing hundreds of tiger snakes on this island permanently blind and hurt at the head. Fortunately for snakes, without eyesight they can "smell" the sugar and the prey with their extremely sensitive tongue. Therefore, the cobra can 'sneak' into the nest of young birds foraging, not starving.
