Orcas( Orcinus orca)

Orcas or Killer whales; three types transients are mammal eaters, residents are fish eaters and third- offshores which are fish eaters too. As for the color of the water, it is reflection of the sky. So. if the sky is blue, the water is blue. If the sky is gray, the water is gray. I found that having an expensive lens can be a disadvantage during very rough seas. I have encountered huge swells from one of the latest trips and I could not hold up my 200-400mm with camera safely to take pictures.. If I had a cheaper one( lighter weight), I would have more better results. Take home message: keep it light and simple.
