Shhh ~ please don't tell anyone that, now I'm volunteering at the California Academy Of Sciences, I paid a visit to the San Francisco Aquarium of the Bay last Thursday!
My picture shows a gigantic school of anchovies dashing over the walkway through the tunnel. Large schools of fish and flocks of swarming birds fill me with admiration and wonder. How do they do it? Who gives the signal? How do they avoid bumping into each other? How do they move as one body? What we do know, is that both the fish and the birds stay together for protection from larger predators. "There's safety in numbers"
