Quote from the Article:

[... said there were good reasons for making a fish-shaped robot, rather than a conventional mini-submarine. In using robotic fish we are building on a design created by hundreds of millions of years' worth of evolution which is incredibly energy efficient," he said. "This efficiency is something we need to ensure that our pollution detection sensors can navigate in the underwater environment for hours on end." The robot fish will be 1.5 meters (nearly 5 feet) long -- roughly the size of a seal. ]

i always wonder the benefit of making a robot fish shape look as REAL?
imaging that - some other bigger fishesssssssssssss swimming by, and then one giant bite later - the $29,000 would be gone pretty fast!
