Orcas, J-pod found just south of Sinclair Island. We counted about 20 individuals and we were lucky enough to see a calf. We were able to see the orange-ish pigmentation. We were also able to identify J-1, Ruffles. They seemed to be in a sleep pattern. Orcas are voluntary breathers so they exhibit unihemispheric sleep. This sleep pattern allows 1/2 the brain sleep while the other 1/2 is awake.
