Whales just want to say hello


Who wants to go swimming with sperm whales? Their sonar is so intense that they can kill animals with a focused click, but here are some free divers playing with them.

(The video overstates some of its inferences — you can’t predict higher brain functions from the presence of spindle cells, or simply from the size of the brain — but it’s still powerful stuff.)

That’s some adaptation they’ve got, and still we killed them to scoop out the oil in their heads.

    …you can’t predict higher brain functions from the presence of spindle cells, or simply from the size of the brain…

    But the extent of sophisticated acoustic signal processing, almost certainly well into the symbolic analysis level, implies a hell of a lot.
