Most galliwasps are larger lizards, with normally proportioned and complete limbs. They superficially resemble
skinks
Skinks are a type of lizard belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of liz ...
