Marty’s photo of the day #5174: On my second morning of photographing orca whales from the beach in front of Deb’s and my Johnstone Strait campsite, I noticed two smaller marine mammals between me and the big orcas. I initially thought they were baby orcas. Later, when I reviewed my photos, I could see they had two-tone dorsal fins. They weren’t baby orcas. Instead, they were adult Dall’s porpoises.
