Population: 90 wild individuals and 44 individuals raised in captivity (2004), 134 individuals, INCREASING


Brief Description

Within the Canary Islands near Spain, the once thought to be extinct La Gomera Giant Lizard, Gallotia bravoana, lives on less than one hectare (<0.01 sq km or <0.004 sq mi) of the island of La Gomera. Once roaming the entire island, this species is now restricted to dry cliffs with scattered vegetation in the shrubland areas. The La Gomera Giant Lizards are diurnal animals that spend most of their days from mid-mornings to afternoons foraging and basking in the sunlight. Although sub-adults may consume some insect larvae, the species is generally considered herbivorous.

They possess a blackish-brown back covered with black, smooth and abnormal scales. Also, two lines of small blue spots run along the side with their underbellies appearing ivory white. They can weigh up to half a kilogram (1.1 lbs) and vary in length from 29.5 to 49 cm (11.6 to 19 in) with a snout vent length from 13.5 to 19 cm (5.3 to 7.5 in). Males have larger heads and white throats, but the back of females’ legs are browner. In contrast, juveniles retain a mix of brownish-shades and variation of blue lines on their backs with green tones on their underbellies.

The largest threat to the La Gomera Giant Lizard remains predation by the feral cats and some feral rats. Due to their slow walking, feral cats can easily prey and consume on them, and feral rats endanger the species by eating their eggs. Additionally, hunting and overgrazing by domestic animals helped contribute to a decline within the species. To counter such trends, the IUCN recommends educating local people, conducting more surveys, and regulating the cat population within proximity to their site. Currently, a captive breeding program is aiding in recuperating and increasing the population, but this alone will not be enough to save this species.

Fun Facts

  1. To attract females, males inflate their throats and bob their heads up and down

  2. The females lay clutches annually of 3-7 eggs

  3. Less than 50 members are adults and most populations are severely fragmented, classifying them critically endangered

  4. In June of 1999, the lizards were documented and declared to be still extant as scientists labelled them extinct due to the lack of sightings
