Scientists and conservationists are once again puzzled over the behaviour of whales - with two different pods of pilot whales beaching themselves this weekend on either side of the Atlantic.
A pod of 26 pilot whales stranded themselves off the coast of Fife in Scotland.
Crowds of on-lookers gathered to watch the massive rescue and relief operation.
13 of the 26 whales did not make it.
And in a strange coincidence... another pod of whales beached themselves along the coast of south-central Florida in the U.S.
This time, 22 pilot whales stranded themselves near Fort Pierce.
Only five whales survived.
