From translingual Lacertidae.
Noun
[edit]lacertid (plural lacertids)
- Any lizard of the family Lacertidae.
- 1993, George R. Zug, Herpetology: An Introductory Biology of Amphibians and Reptiles, page 427:
- Lacertid scalation and body forms are similar to those of the teiids, although lacertids are usually smaller.
- 2004, Daniel A. Greenberg, Lizards, page 33:
- Lacertids are distinguished by a section of large, flat scales on the undersides of their necks. […] Teiids are the New World counterparts to lacertids.
- 2006, Eric R. Pianka, Laurie J. Vitt, Lizards: Windows to the Evolution of Diversity, page 206:
- Lacertid teeth are hollow at the base (teiid teeth are solid). Virtually all lacertids are terrestrial or rock-dwelling lizards, although a few species, including Holaspis and Takydromus, climb in vegetation, and at least one species appears to live high in trees.
