Such an odd species - no dorsal fin, long and thin body with tiny flukes only a foot across. But boy can they speed! First time seeing them today, what a treat. I posted a video to Facebook of them porpoising: https://www.facebook.com/robin.agarwal.14
A real treat. Cooperatively feeding very close inshore (these photos were taken from the bluff). This group of about 18 dolphins repeatedly circled fish into a nice bait ball before moving in. An outlier occasionally breached as they followed the fish, perhaps to scare fish closer to the pod? Or just fun?
