La Palma Giant Lizard
It probably lives in xerophytic vegetation and is presumably an egg-laying species. Long believed extinct (and likely will remain classified as such until the Red List is updated), it was rediscovered in 2007.
Its decline started 2000 years ago with the arrival of humans on La Palma.
Until its recent rediscovery, it was believed to have become extinct in the last 500 years. The main causes of this presumed extinction were believed to have been introduced cats, consumption by people, and habitat destruction for agriculture.
It is not the only lizard from the Canary Islands to have been considered extinct only to be rediscovered later: This happened with other giant lizards of the Canary Islands, like the El Hierro and La Gomera Giant Lizards (rediscovered 1974 and 1999, respectively); the somewhat smaller Tenerife Speckled Lizard was only discovered for the first time in 1996.
This giant lizard was originally described as a subspecies of the El Hierro Giant Lizard (Mateo et al 2001). The recently discovered individual of the La Palma Giant Lizard was slight more than 30 cm (~1 ft) long and had an estimated age of four years. New expeditions to the area of the rediscovery are planned in the hope of finding more individuals and possibly a breeding population.
Unfortunately, the present material of G.
Probably it belongs to the simonyi clade like the other giant Gallotia species from the western islands, but whether it actually was as close to G. The reason for this is also that it was only discovered after the present species' description that G.
