A Dolphin and a Whale

Here's a dolphin and whale doing...something quite different, according to this expert, which we'd like to interpret as a cute, cuddly dance, but the ocean is vast and brains are weird and deep and we really don't know, given that these species are millions of years old and here long before us. We can't at all expect this behavior is just now being seen for the first time, given the size of the ocean and the lifetime of these species....

Still, it's delightful!
