The whales probably aren’t really trying to talk to us. But there is a good chance that they use those low frequency sounds to talk to each other. And being able to get their messages to each other is probably very important for their livelihood – they might be telling each other about a delicious krill buffet. Or maybe they need to attract mates with a whale-themed pick-up line. Either way, it’s kind of bad if the noise in the ocean is so loud that they can’t hear each other.
HAPPY BIRTHDAY, DAX!
