In vertebrates, the relative proportion of the number of trunk and caudal vertebrae is an
important determinant of body shape. While among amphibians frogs and toads show low …

Morphology is among the most important traits influencing the interaction of individual
animals with their environments. Fossoriality reflects this functional association between …

Limb-reduced and limbless scincid lizards pose problems in untangling their relationships
because of a strong tendency toward convergent evolution in which functional characters …

In mammalian vertebral columns, locomotive ability is expected to be an evolutionary driver
of variation in the number of vertebrae; in species evolved to run fast or have a flexible …

The threadsnakes of the family Leptotyphlopidae have been historically neglected in terms
of their natural history, ecology, systematics, and morphology. Given the relevance of …

This contribution qualitatively and quantitatively analyses vertebral microanatomical features
based on virtual sections of numerous amniote dorsal vertebrae obtained from conventional …

Squamates exhibit a vast diversity of body plans, which directly determines habitat use and
preference. Here the skeleton of the sand‐swimmer burrower gymnophthalmid …

Background The tetrapod limb is a highly diverse structure, and reduction of the limbs
accounts for much of the phenotypes observed within species. Squamate reptiles represent …

The lizard genus Psilophthalmus was originally described from the sandy deposits at the
northern end of Serra do Espinhaço, in Santo Inácio, state of Bahia, but since then it has …

We present a detailed anatomy of the pectoral girdles, pelvic girdles, and hindlimbs of adult
and juvenile specimens of Pseudopus apodus (Pallas, 1775). We compared the individual …
