The Many-lined Sun Skink (Eutropis multifasciata) looks like a lizard of the family Lacertidae (sometimes called true lizards), but like most species of skinks it has no pronounced neck and relatively small legs.
It is native throughout many Asian countries. 
The colour of the flanks can vary from olive-brown to reddish-orange.
The throat colour can vary from white to yellow.
Being non-venomous and diurnal in nature, it is an active animal and feeds mainly on insects and gives birth to live young.
