Morphology

Sphenodon + punctatum

This is a Latin binomial (scientific name) and functions as a taxonomic proper noun rather than a compositional English phrase; the meaning ‘a species of reptile (tuatara)’ requires domain knowledge of taxonomy. One constituent ('punctatum') is not an English word in the dictionary and the genus name is specialized, so a B1 learner who knows common English vocabulary would not be able to derive the biological species meaning from the parts alone.

Etymology

Sphenodon punctatum comes from old words: Sphenodon means 'wedge' and 'tooth' because of its wedge-shaped teeth, and punctatum means 'spotted'. So the name gives a simple picture of this rare, very old reptile and helps explain why it is the only living member of its group.
