RHYNCHOCEPHALA Meaning and
Definition
-
Rhynchocephala refers to a small reptilian order comprising the tuatara, the only extant members of the group. The name "Rhynchocephala" is derived from the Greek words "rhynchos" meaning "beak" and "kephale" meaning "head," which alludes to the distinctively beak-shaped snout that characterizes these reptiles.
Rhynchocephala encompasses two recognized species: Sphenodon punctatus and Sphenodon guntheri. These reptiles are endemic to New Zealand and exhibit several primitive, lizard-like traits. They have a similar external appearance to lizards but possess distinct anatomical features that set them apart. Notably, they have a unique dentition comprising two rows of teeth on the upper jaw and one row on the lower jaw.
Another distinctive characteristic of the Rhynchocephala is their remarkable and ancient lineage. They are considered a "living fossil" because they represent the only surviving members of a once-diverse group of reptiles that flourished during the Mesozoic era, alongside dinosaurs. The tuatara has remained evolutionarily conserved for millions of years, illustrating remarkable unchanged morphological features.
Rhynchocephala are known for their slow metabolism and prefer cooler temperatures, often living in burrows or crevices. They primarily feed on insects and small vertebrates, relying on their keen vision, acute sense of smell, and unique method of capturing prey. Additionally, tuataras have a characteristic third eye, or "parietal eye," on the top of their head, which serves a different function than their other two eyes.
Due to their evolutionary significance, the Rhynchocephala have garnered attention from researchers studying the mechanisms of animal evolution and biology
