A common species of glass lizard, the Slender Glass Lizard (Ophisaurus attenuatus), can reach an impressive length of two to three feet (60-90 cm) in overall length.
Understanding Glass Lizard Size
Among the various species of legless lizards commonly known as glass lizards, the Slender Glass Lizard stands out as a particularly long example. Adults typically measure within the range of two to three feet, making them quite sizable reptiles. For instance, in places like Indiana, this species holds the distinction of being the largest native lizard. This considerable length is a significant characteristic, contributing to their unique appearance.
| Measurement Type | Range (Feet) | Range (Centimeters) |
|---|---|---|
| Overall Length | 2 to 3 feet | 60 to 90 cm |
Distinguishing Characteristics of Glass Lizards
Glass lizards, despite their snake-like appearance due to their lack of legs, possess several key features that clearly identify them as lizards. They are remarkably unique reptiles and are almost impossible to mistake for other species once their distinguishing traits are known.
Key identifiers include:
- Movable Eyelids: Unlike snakes, glass lizards possess movable eyelids, allowing them to blink.
- External Ear Openings: They have visible external ear openings, which snakes notably lack.
- Non-Forked Tongue: Their tongues are typically notched rather than deeply forked like those of many snake species.
- Ability to Detach Tail: True to their name, glass lizards have a very long, fragile tail that can break off as a defense mechanism when grasped. This tail can sometimes shatter into several pieces, giving rise to the "glass" moniker. The tail can regenerate, though often not to its original length or appearance.
Habitat and Identification
Slender Glass Lizards, like many glass lizard species, typically inhabit grasslands, open woodlands, and prairies. Their unique morphology and considerable length make them a distinctive sight in their natural habitats.
