“Our holiday was in Mid September. We have shared stories of our stay ever since and will continue to do so, as our host John Reid with his wife & team gave us the benefit of truly unforgettable experiences. From the greeting off the seaplane with the three other couples on our flight, a massive bowl of sea food with all guests, a short walking tour to a nearby building (to listen to its history), a glorious meal, comfortable & relaxing accommodation, motorboat trip to find ourselves right where the killerwhales passed by (playing around our boat…Glenn was a gem as his love of the marine life was evident), beautiful lunch, another superb meal and on the third day a motorboat / minibus trip to our best ever wildlife experience….grizzlies and cubs feeding on wild salmon…our photos need no commentary, to a leisurely afternoon where I won a tee shirt (golf shot from front lawn to nearest a selected object) and John saw as off back on the seaplane.”
The website “eHow” provides the best explanation of “How Do Killer Whales Sleep?”“Like dolphins, killer whales are voluntary breathers, meaning their breathing is not automatic like it is for humans. Instead, they must consciously rise to the surface and breathe. This makes sleeping for them much different than it is for other animals. Studies on dolphins and beluga whales have shown that they sleep by shutting down only one hemisphere of the brain at a time, thereby allowing them to both rest and have control over their breathing. It is thought that killer whales, being closely related to dolphins, do the same thing. Resting behaviors differ depending on whether the killer whale is by itself or part of a pod. If it is alone, it will rest by staying near the surface, with dorsal fin, blowhole and part of the head out of the water. Usually this only lasts for a few minutes at a time, but there have been reports of killer whales resting this way for up to eight hours.Killer whales in pods sleep differently. The pod will form a tight circle, and their breathing and movements will synchronize. They take several breaths at the surface, and then submerge for a period of time before surfacing again. The time spent submerged increases as the “sleep” becomes deeper, and they may take up to ten breaths near the surface before submerging for as long as ten minutes. Pods resting like this will avoid boats and contact with other animals during this process. It is thought that this kind of group resting may strengthen the animals’ bond and cohesiveness as a unit.”
