"I believe I speak for the entire human race when I say, 'Holy fuck,'" said Oceanographic Institute director Dr. James Aoki, noting that the dolphin has a cranial capacity 40 percent greater than that of humans. "That's it for us monkeys."

Delphinologists have reported more than 7,000 cases of spontaneous opposable-digit manifestation in the past two weeks alone, with "thumbs" observed on the bottle-nosed dolphin, the Atlantic humpback dolphin, and even the rare Ganges River dolphin.
"It appears to be species-wide," said dolphin specialist Clifford Brees of the Kewalo Basin Marine Mammal Laboratory, speaking from the shark cage he welded shut around himself late Monday. "And it may be even worse: We haven't exactly been eager to check for thumbs on other marine mammals belonging to the order of cetaceans, such as the killer whale. Oh, Christ, we're really in the soup now."
Thus far, all the opposable digits encountered appear to be fully functional, making it possible for dolphins–believed to be capable of faster and more complex cogitation than man–to manipulate objects, fashion tools, and construct rudimentary pulley and lever systems.
