Morphology
Raja + erinacea
This is a Linnaean binomial: the first element 'Raja' names the genus (skates), so a learner who knows that constituent can infer it refers to a species of skate. However, the specific epithet 'erinacea' is not an English lexical item (no transparent meaning provided), and the precise sense (small size, range, seasonality) cannot be derived from the parts, so the compound is only partially inferable.
Etymology
Raja erinacea is the Latin name for a small skate. The name may come from the two parts Raja, an old word for a 'ray', and erinacea, from a word for a 'hedgehog', because this little skate has rough, slightly spiny skin, so the name describes this inshore species.
