Naturalist Paul Jones answers the Mystery Monday challenge!

This is the majestic blue whale, which can be identified by its steel-blue color and its enormous size. When a blue whale surfaces, you see back, back, and then more back until the small, triangular dorsal fin emerges and indicates the full size of this giant. In this photo are also remoras, peculiar fish with a sucker mouth that hitchhike on whales, dolphins and even whale sharks.
