Dolphins aren't endangered.
They are only as intelligent as a 5-10 year old(or possibly me) human child, with capacity for problem solving, reasoning and the like. They also have verbal communication which we, as the supreme rulers of this rock, don't care to learn because, well, they taste so good.
Yum.
Ok, so why is it secret and if it's so important that these lovely creatures be saved, how come those surfers didn't go all the way? I mean, choose one to "distract" the propellor on that boat while the others cut the nets, no?
Can't Claire grow back her limbs?
SAVE THE DOLPHINS SAVE THE WORLD!
And thanks for all the fish.
