The Roque Chico de Salmor giant lizard is a subspecies of El Hierro giant lizard and is believed to be extinct. It was once present throughout much of the El Hierro island in the Canary Islands of Spain and on the small offshore Roque Chico de Salmor. Hierro giant lizards are thick lizards and reach about two feet long, and their heads are broad. Adults are dark gray to brown in color with pale orange patches running along the sides. Their undersides are mostly brown but have orange to red colorations towards the middle. As they grow old they turn black in color with some shades of gray. Males grow larger than females.
Hierro giant lizards are terrestrial lizards and seem to prefer rocky habitats preferably in small and young volcanic areas. They are omnivorous and feed on two main plant species, Kleinia neriifolia and Lavandula abrotanoides. They also feed on insects. To impress females, males bob their heads with their throats inflated. Mating occurs in May, and the female gives birth to 5 to 13 eggs between June and August. The eggs are incubated until they hatch 61 days later.
The Roque Chico de Salmor giant lizard subspecies was wiped out from the Roque Chico de Salmor in the 1930s due to overcollection of specimens for scientific study and for its commercial value. A recovery plan has been developed along with a captive breeding program by the Canary Islands Autonomous Government for all remaining Hierro giant lizard subspecies, and they are also legally protected both nationally and internationally.

Eight Species Declared Extinct But May Still be Out There1. Tasmanian Devil
The Tasmanian devil is endemic to Australia. Although this species is called tiger (named for its stripes) and wolf (due to its canid-like appearance), it is not a member of the cat or wolf family. It is a member of the marsupial family. Other members of this family include kangaroos and koala bears.
The last known Tasmanian tiger died in a zoo in Hobart, Tasmania in 1936, but there have been hundreds of unconfirmed sightings, and a reserve has been set up in Southwestern Tasmania in the hopes that possible surviving individuals can have adequate habitat.
