All of the species have soft, pithy wood. Scalesia species have been called "the Darwin's finches of the plant world" because they show a similarly dramatic pattern of adaptive radiation. One of the largest and most widespread species is Scalesia pedunculata – a large tree which grows up to 15 to 20 metres tall, reaching maturity in a few ...

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. It was after visiting the Galápagos and studying the wildlife that a young Charles Darwin developed his theory of evolution. [2]

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.
Opuntia galapageia is a species of cactus. It is endemic to the Galápagos Islands, part of Ecuador. Forms occurring on different islands have been treated as separate species and subtaxa of these species. Opuntia echios, Opuntia helleri, Opuntia insularis, Opuntia megasperma, Opuntia myriacantha and Opuntia saxicola are now sunk within O ...
