The whales are sending us good vibes.
I see at the ship yards when the skimmers are in port there are all kinds of precautions taken when a diver is down so the ships sonar is not turned on due to killing the diver.
Sure Whales talk, but so do wolves that send their message out into the night on a full moon.
Crows have a language and a set social life----Not a flock of Crows but a Murder of Crows.
Whales are social animals, as such they must communicate with one another so they do so with sound. When a Pod is minding its own business and find their language is being scrambled by some unknown source to them, those that do beach themselves or get lost from the Pod will likely die.
I find it amazing that this animal has changed frequency over the years. This takes some kind of understanding of survival and intelligence.
As our sonar gets more and more lethal to these beasts, their pattern of migration may change, they may in time learn to recognise a submarine as an enemy.
Few people realise that Moby Dick was written about a real life incident that took place, actually the accounts of the reality made the story as we read or see on film look like a cake walk.
