The finding may help explain some of the behaviours seen in whales, such as ... tool usage, the researchers report in The Anatomical Record.

I've give a shiny new nickel for ONE picture of a whale using a Hammer.

LOL, that's what I was thinking. Can we get an example please? Unless they think the humpbacks' "bubble curtains" that they make when feeding are some kind of tool, I can't think of anything close I've ever heard of before.

Oh, yeah.....and the "tool usage" thing is just a crude reproductive metaphor.
