We spent two weeks on a cruise in the Galapagos. We visited eleven islands with multiple stops on several islands. It was a trip of a lifetime. I am not a birdwatcher, but the ‘only place on earth’ birds were great. Blue-Footed Booby, Red-Footed Booby, Nasca Booby, magnificent frigatebird, penguins, Albatross, flightless cormorant, several species of mockingbirds, Galapagos Dove, Lava Heron, Great blue heron, Flamingos and ten or more different species of Finches, hawks and more. It was difficult to keep track. The Birders were in heaven.
As much as enjoyed the birds the sea life was much more to my liking. Playful sea lions, dolphins, sharks, sea turtles, and a hundred different kinds of fish. I liked the puffer fish, Angel, hawkfish, yellowtail surgeonfish, marble ray, white-tip reef shark, Blue-Chin Parrotfish, and a purple and yellow fish I cannot remember. - Ah, King Angelfish and so many more.
On land we had the land and sea iguanas, and of course the tortoises. We tortoises them on five different islands (Santa Cruz, Fernandina, Floreana, Espanola, and San Cristobal) and they were different species. There are ten remaining species, but I don’t think I saw them all. Many of these species are unique to the Galapagos. It is what makes it unique.
