ANTARCTIC "Seal Cam" Images

I have seen "turtle cam" before. Scientists view the habitat and the organism they are studying from the back of the Weddell Seal, so they can also study the habits of the seal without having to kill anything.
Why not do this to whales? Gosh, think how many cameras you could connect to a whale and have WHALE-A-VISION. It could be an excellent way to study their feeding habits and other patterns of behavior. Could record sounds also.
Can someone suggest this to prevent whale killing?

Seal cam is an on-going National Science Foundation scientists use seals as "eyes" to see what goes on underneath the Antarctic ice Weddell seals are a predator of the toothfish. Toothfish are found throughout Antarctica and the Antarctic Peninsula, South Orkney Islands and South Shetland Islands, from 0 to 695 meters depth. A well-adapted hunter, the lateral line sensory system of the toothfish can detect prey by recognizing the low vibration frequencies emitted by swimming crustaceans.
