While reading a bit about these cables I found this unusual fact on Wikipedia:
> Because the [TAT-8] cable was the first fiber optic cable and not coaxial cable, the electrical interference shielding for the high voltage supply lines was removed. This removal did not affect the fiber, but it did cause feeding frenzies in sharks that swam nearby. The sharks would then attack the cable until the voltage lines killed them. This caused numerous, prolonged outages. Eventually, a shark shielding was developed for the cable.

- bane 15y agoInteresting factoid, Sharks have a fairly unique sense that most animals don't, they can sense fairly faint electrical fields that living creatures produce (electroreception) that they use for "targeting" their amazing jaws, finding prey hidden in seafloor sand, and possibly even navigating in Earth's magnetic field. This is especially important when they are about to attack some prey. Due to the structure of their jaws that actually unhinge and push forward during an attack, they lose sight of their prey and use this sense to hone in their bite. I remember watching video from an experiment where Sharks were fed live fish and raw meat, and the sharks kept missing the meat but almost never missed a live fish. Here's a video of one confused by an artificial electrical field. http://www.youtube.com/watch?v=4aYPHeK1Tyo http://www.youtube.com/watch?v=4aYPHeK1Tyo
