Folks, those are very clearly whales. The one on the left is a calf and the one on the right is likely its mother. Not sure of the species but they are definitely baleen whales. Look at the v-shape indention on the front (towards the top left), corresponding to the long ridge along the top of the skull, and you can clearly see areas of greater contrast around the blowhole on the smaller specimen. The small "cloud" may even be blowhole blast.
I don't think the picture found on Tomnod is clearly or obviously anything, and hopefully it is followed up on unless there are more detailed images available that identify the object as something as other than an airplane. While I intuitively think it unlikely that the plane would have gone into the water as intact as the object shown on the image, it does have enough similarities that it would seem to be as much of a possibility as any of the other crazy theories being thrown out there. Particularly, the appearance of a possible portion of the right wing in the image that matches very well with the 777 overlay is somewhat intriguing.
