Trunk vertebrae of Triturus newts differ in size and shape.
- class="label">•
Allometry contributes to the variation in vertebral shape within species.
- class="label">•
Body elongation is achieved through an increase in the number of trunk vertebrae.
- class="label">•
Interspecific differences in vertebral shape are correlated with this pattern of elongation – more elongated species have more gracile vertebrae.

Shapes of individual vertebrae are distinct among species and can serve for identification purposes.
