whales have always been such beautiful, mysterious creatures for me. I can't imagine the terror of seeing one out at sea if you didn't know what it was. But the truth, that they are gentle giants, is so lovely. Gentle giants are my favorite.
Apparently, male blue whales songs have been slowly getting less loud and deeper over the last few years. Supposedly it is because their sizes are getting bigger (or they want to sound bigger) so their mating calls are changing, but no one has come up with a definitive answer. It is happening with blue whales worldwide, so they are listening to each other and being influenced by each other. It's like a cultural phenomenon! What a strange thing, for their songs to change.
