In Madagascar and nearby islands of the Indian Ocean some of the most visible reptiles are the various species of Phelsuma geckos. Usually referred to as day geckos (although at least one species on Mauritius is nocturnal) they are mostly small lizards, living in trees and bushes. There are numerous species, many with ranges limited to a single island or patch of forest, and consequently many are classed as threatened or worse by the IUCN. At least 2 species are extinct, one of which was the largest known species, the Rodrigues Giant Day gecko, which reached at least 40cm. .
At Bristol, 2 species are on display, the tiny Yellow-Headed Day Gecko P.klemmeri and Standing’s Day Gecko P.standingi.
