This pineapple-looking floating object is either a limb from a giant amphibian, or the root system of what is commonly referred to as a lily pad. Don't show this to the Russians, it's probably edible.
You won't see this too often......a swimming eagle. Perhaps having a brisk "dip" on a hot day, or just a case of not stopping before hitting the water. Either way, he / she looked a little "p-o'ed".
