Tiny Lizards Found in Madagascar

One of the world's tiniest lizards has been discovered by keen-eyed researchers in Madagascar.The miniature chameleon, Brookesia micra, reaches a maximum length of just 29mm.
German scientists also found a further three new species in the north of the island.The lizards were limited to very small ranges and scientists are concerned they could be at risk from habitat disturbance.

The geckos Sphaerodactylus ariasae and S. parthenopion are considered to be the smallest lizards in the world with adults just 18mm long

This phenomenon occurs when a species becomes smaller over evolutionary time in order to adapt to a restricted habitat such as an island.
