If submariners want to see what's up there, however, they really have no choice ... although that may be about to change.

Although that's partly because stuck turtles rarely make the news, it's also due to the fact that they're relatively small and highly maneuverable. With that in mind, the European Union-funded ARROWS project has created U-CAT – a prototype robotic sunken-ship-exploring sea turtle. Read More
