musical discussions with whales

i found this article to be very intersting. it made sense to me how the people at IC recommended that musc would serve well at the foundation for contact with whales.
i also learned a ton about whales. for example, i learned that on the island of Shikoku, the month of June is where the serm whales venture close enough to shore to observe their passage. i guess it makes sense though, because most animals, such as birds, have a migration pattern. So why shouldn't whales?

I also learned that whales communicate by echolocation, which is similar to sonar. i origonally thought that they spoke with their huge mouths in whale language. but they dont. they use echolocation. sperm whales are cool.
