Morphology

Squalus + acanthias

This is a Latin binomial (genus + species) functioning as a taxonomic proper name rather than a compositional phrase; its meaning (‘a species of small shark’) is an arbitrary label and not transparently built from everyday English words. One constituent is not a normal English word and the other is a scientific genus, so a B1 learner who knows the parts would still not reliably infer the species meaning without prior exposure or specialist knowledge.

Etymology

Squalus acanthias comes from old words: Squalus meant 'shark' and acanthias came from a word for 'spine' or 'thorn'. The name paints a picture of a small shark with a sharp spine on its back, so it refers to the 'spiny dogfish' and is used for that species.
