Isabela Island (Spanish: Isla Isabela) is the largest of the Galápagos Islands, with an area of 4,586 km 2 (1,771 sq mi) and a length of 100 km (62 mi). By itself, it is larger than all the other islands in the chain combined, and it has a little under 2,000 permanent inhabitants. The island straddles the equator.
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. [citation needed] Due to amphibians intolerance of saltwater, no amphibians naturally occur on the Galapagos Islands.
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 island is actually a collapsed volcano that is a nesting location for a variety of seabirds such as Frigatebirds and the elusive Red-Billed Tropicbird, among others.

Isabela Island by the Sierra Negra volcano, one group in the east and another over the western and southwestern slopes. At least one authority has suggested merging C. n. vicina with C. n. microphyes, C. n. vandenburghi and C. n. guentheri as the southern Isabela tortoise (C. n. vicina), putting morphological differences down to geographic ...
Islands such as Isabela Island contained cold and nutrient-rich waters that provided abundant food, ensuring the survival and reproduction of penguins. [10] Over millions of years, the penguins underwent adaptations, developing unique features that enabled their existence and allowed them to thrive under such an ecological niche. [ 10 ]
The land iguanas of Galápagos vary in morphology and coloration among different populations. [6] In addition to the relatively widespread, well-known Galápagos land iguana (C. subcristatus), there are two other species within Conolophus—the Galápagos pink land iguana (C. marthae), of northern Isabela Island, and the Santa Fe land iguana (C. pallidus), of Santa Fe Island.
The Pinta Island subspecies (C. n. abingdonii, now extinct) has been found to be most closely related to the subspecies on the islands of San Cristóbal (C. n. chathamensis) and Española (C. n. hoodensis) which lie over 300 km (190 mi) away, [17] rather than that on the neighbouring island of Isabela as previously assumed.
