parent_taxon dravidogecko
___MASK92___ is an infraorder of squamate reptiles in the suborder Scleroglossa , comprising all ___MASK18___ and the limbless " snake - lizards " of family Pygopodidae . The legless lizards of the family Dibamidae , also referred to as blind lizards , have occasionally been counted as gekkotans , but recent molecular phylogenies suggest otherwise . ___MASK18___ are lizards belonging to the infraorder Gekkota , found in warm climates throughout the world . They range from 1 . 6 to 60 cm ( 0 . 64 to 24 inches ). Most ___MASK18___ cannot blink , but they often lick their eyes to keep them clean and moist . They have a fixed lens within each iris that enlarges in darkness to let in more light . Dravidogecko is a monotypic genus of Indian gecko , commonly known as forest gecko . Lizards are a widespread group of squamate reptiles , with over 6 , 000 species , ranging across all continents except Antarctica , as well as most oceanic island chains . The group , traditionally recognized as the suborder Lacertilia , is defined as all extant members of the ___MASK99___ ( reptiles with overlapping scales ) that are neither sphenodonts ( i . e ., tuatara ) nor snakes  they form an evolutionary grade . While the snakes are recognized as falling phylogenetically within the ___MASK82___ clade from which they evolved , the sphenodonts are the sister group to the squamates , the larger monophyletic group , which includes both the lizards and the snakes .
