The potent venom in this banded sea snake can kill a scuba diver.
So most underwater predators leave snake off their daily menus.
Their real danger comes from the sky.
Snake Island, off the coast of Malaysia.
This little chunk of limestone plays host to hundreds of sea snakes.
It's placid right now, but don't be fooled.
These snakes have come ashore to breed and tonight, the competition on this island for potential mates will be fierce.
Sea snakes usually spend most of their time in water, but they don't have gills.
Their lungs stretch almost the length of their entire bodies.
To fill them, they have to swim to the surface to breathe.
And that means they're vulnerable.
This white-bellied sea eagle has young to feed...so it's on the hunt.
Armed with keen vision and sharp talons, the eagle has perfected the snatch-and-grab.
And sea snake is one of her favorite foods.
But this snake isn't about to play the victim.
As the eagle flies towards the nest with her prize, the snake starts to fight back.
Even in mid-air, he can bite.
If he manages to inject his venom, he could kill his abductor.
But biting an enemy in mid-air isn't easy, especially for a creature that spends most of its time in the water.
For this snake, it's too little, too late.
