Marine Iguanas, sea lions, fur seals, land and sea turtles, flamingos, dolphins, and sharks are found here. There are a large number ofgoats and pigs, animals which were introduced by humans to the islands and have caused great harm to the endemic species. Darwin Finches and Galápagos Hawks are usually seen as well as a colony of Fur Seals. At Sullivan Bay, a recent (1897) pahoehoe lava flow can be observed.
Puerto Egas, south of James Bay and west side of Santiago, is one of the best sites. There is a long, lava shoreline where eroded rock formations house an excellent variety of wildlife. Marine iguanas bask in the sun while land iguanas scatter around feeding on exposed algae. The tide pools contain many Sally Lightfoot crabs, which attract other types of hunters. Following the trail Fur seal lions are found. Puerto Egas is not only a good spot for taking pictures but also perfect for snorkeling and seeing many species of tropical fish.
Sullivan Bay is especially fascinating for those who are interested in geology and volcano logy. You can walk over the uneroded, black lava flow covered with lava bubbles and tree-trunk molds in the surface. There are two small beaches where turtles come for nesting.
Cousin's Rock is a well known dive site and is situated off the east coast of Santiago. It is a triangular rock that rises about 10m out of the water and is made up of many layers of volcanic rock
