Devices are put on Blue Whales so that scientists can track them and understand their migration patterns. Its like a chip, (horrid things, aren't they)? Instead of going inside the whale its sticks to the skin, they will fall off eveentually, but it doesn't hurt them because they have such thick blubber.
