The most dominant plant species in the Teide National Park are the Teide white broom (Spartocytisus supranubius), which has a white and pink flower; the Canary Island wallflower (Erysimum scoparium), which has white and violet flowers; and the Teide bugloss (Echium wildpretii), whose red flowers form a pyramid up to 3m in height.
The Teide National Park contains a huge range of invertebrate fauna, over 40% of which are endemic species, with 70 species only being found in the national park. The invertebrate fauna include spiders, beetles, dipterans, hemipterans, and hymenopterae.
In contrast, Teide national park has only a limited variety of vertebrate fauna. Ten species of bird nest in the park.
Three endemic reptile species are also found in the park – the Canary Island lizard (Gallotia galloti galloti), the Canary Island wall gecko (Tarentola delalandii), and the Canary Island skink (Chalcides viridanus viridanus).
The only mammals native to the park are bats, the most common species of which is Leisler's bat (Nyctalus leisleri). - in: wikipedia

Mount Teide is a volcano on Tenerife in the Canary Islands, Spain. Its 3,718-metre (12,198 ft) summit is the highest point in Spain and the highest point above sea level in the islands of the Atlantic. It remains active: its most recent eruption occurred in 1909 from the El Chinyero vent on the northwestern Santiago rift. Teide, Pico Viejo and Montaña Blanca form the Central Volcanic Complex of Tenerife.
Teide is the most visited natural wonder of Spain, the most visited national park in Spain and Europe and – by 2015 – the eighth most visited in the world. - in: wikipedia
