The Green Turtle

Faster than a cheetah in water

He slowly swims towards the jellyfish

It stops

So does the Great Green Turtle

The jellyfish sees nothing, and sways on

The Green Turtle resumes and swims faster yet

CHOMP

He gobbles the jellyfish

Only to realise, 

It was a plastic bag

Will the last of them live till 80

Or will they leave the world at 10
