On a recent walk I noticed some disturbance in the water not far offshore and was happy to see a school of 15 to 20 spinner dolphins. I thought they were headed south and set out to follow them from shore. Then they turned around and went north again. I followed. This happened several times, so I just sat down and watched while they tried to make up their minds.
Spinner dolphins get their name from the twirls they make when they leap from the water. It’s thought this activity helps dolphins know where others in the school are because the bubbles generated by their takeoff and return to the water are a good target for their echolocation.

As soon as I read the email and saw “dolphin” I just knew you would work a “school of fish” into this theme. Now why didn’t I think of that? Nice photos of these dolphins, I love seeing them!

I’m nothing if not predictable. I thought this was one challenge I’d have to skip, but when I saw the dolphins I couldn’t resist. One of my highlights in Hawaii has been swimming with the dolphins a couple of times when they were in a bay near where I was staying.
