Since water absorbs light, colors fade as you go deeper. A red fish, for example, looks black below 30 feet. Moorish Idols stayed near the bottom, pecking around the rocks and barnacles in search of food. The Sergeant Majors fed on plankton near the surface. In a single breath, I could see fish from opposite ends of the earth.
Islands sit at a crossroads where five major ocean currents come together.
These currents have brought most of the sea life to the Gal pagos. For example, today we saw the Yellowtail Surgeonfish, which arrived here with the Panama Flow, a moderately warm water current, that starts off the west coast of Panama. We also saw Moorish Idols, which came to the Gal pagos on the warm North Equatorial Counter Current from the west Pacific. Even my sea lion friends have made a journey. Their early ancestors probably came from the California coast, with yet another current, the North Equatorial Current.
