Lizards are interesting animals.  There are over 6000 species that live on all continents.  What an amazing animal. 
Oh really. I never know we have so much diversified species. 
Yes, there are quite a few different ones.  They range in size from just a few centimeters to a few meters long.  They can get large!
What is the maximum size for a lizard
legless, and have long snake-like bodies. Some such as the forest-dwelling "Draco" lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with brightly colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals as big as water buffalo.
Lizards make use of a variety of antipredator adaptations, including venom, camouflage,
unique among vertebrates in that the pectoral and pelvic girdles are inside the ribcage rather than outside. Tortoises can vary in dimension from a few centimeters to two meters. They are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. Tortoises are the longest living land animal in the world, although the longest living species of tortoise is a matter of debate. Galápagos tortoises are noted to live over 150 years, but an Aldabra giant tortoise named Adwaita may have been the longest living
