Due to the lack of natural predators, the wildlife in the Galápagos is extremely tame and has no instinctive fear. [1] The Galápagos Islands are home to a remarkable number of endemic species. The stark rocky islands (many with few plants) made it necessary for many species to adapt to survive and by doing so evolved into new species.
The Galapagos hotspot has a very complicated tectonic setting. It is located very close to the spreading ridge between the Cocos and Nazca plates; the hotspot interacts with both plates and the spreading ridge over the last twenty million years as the relative location of the hotspot in relation to the plates has varied.
This is a list of animals that live in the Galápagos Islands.The fauna of the Galápagos Islands include a total of 9,000 confirmed species. Of them, none have been introduced by humans, and seventeen are endemic.
Without tourism on the Galapagos Islands, animals are free to inhabit the once human-occupied spaces. Researchers discover that wildlife is reclaiming the Galapagos after tourism stalls Skip to ...
The devastating El Niño of 1982–83 saw almost six times as much rain as normal in the Galapagos and created a wildlife catastrophe. [91] The 1997–98 El Niño adversely affected wildlife in the waters surrounding the islands, as the waters were 5 °C (9 °F) warmer than normal.
Coastal lakes, moist soil and areas where freshwater and seawater mix contain unique species still to be studied. Cold, hot and warm marine currents come together here, generating a wide diversity of animal life: from small coloured fish to large mammals: [3] marine iguanas, Galapagos land iguanas, galapagos crabs, Galápagos sea lion, Sharks, Blue footed boobie, swallow-tailed gulls, ducks ...
The islands are home to 29 native species of land birds, 24 of which are endemic. Endemic species include the Galapagos hawk (Buteo galapagoensis), Galapagos dove (Zenaida galapagoensis), Galapagos rail (Laterallus spilonota), Galápagos martin (Progne modesta), and four species of mockingbirds from genus Nesomimus.

Brown and Wilson viewed character displacement as a phenomenon involved in speciation, stating, "we believe that it is a common aspect of geographical speciation, arising most often as a product of the genetic and ecological interaction of two (or more) newly evolved, cognate species [derived from the same immediate parental species] during ...
