It has begun!

So, the dolphins have made the first move in our little game for survival, eh? When the finned menace reaches our shores, there will be no stopping them.

Armed dolphins, trained by the US military to shoot terrorists and pinpoint
spies underwater, may be missing in the Gulf of Mexico.
Experts who have studied the US navy's cetacean training exercises claim the 36 mammals could be carrying 'toxic dart' guns. Divers and surfers risk attack, they claim, from a species considered to be among the planet's smartest. The US navy
admits it has been training dolphins for military purposes, but has refused
to confirm that any are missing.

Plus, I hear that they now have opposable thumbs. Opposable thumbs and dastardly plans!

Between the superintelligent brains and the advanced armament systems...well I for one would like to welcome our new dolphin overlords and remind them that I can be of use in convincing my fellow Surface Dwellers to labor in their underwater kelp fields. Also, I buy the safe tuna. Just throwing that out there.
