I really don't think those orcas are playing..... I think they are trying to work out how they can land on the fast moving iceberg and eat the very large squealing 'Penguins' stood on the back of it......
Orcas are amazing. I was recently lucky enough to have a close encounter of the Orca kind,
without even being on a boat
I saw Dolphins up close in the boat recently and they are a lot larger in real life, being up close with Orcas would be probably more terrifying than exciting :-)
I'm guessing those pics were taken stateside ? Very nice :-)
