Morphology
Carcharhinus + obscurus
This is a Latin taxonomic binomial: the genus Carcharhinus identifies a group of sharks and the species epithet obscurus (Latin for 'dark' or 'dusky') serves as a descriptive adjective. If a learner actually knows both constituent meanings (including the Latin obscurus) they can infer 'dusky shark', but because the species epithet is non‑English and not in ordinary learner dictionaries, the composition is only partially transparent to a B1 learner.
Etymology
Carcharhinus obscurus comes from old Greek and Latin words. The part Carcharhinus points to a 'sharp' nose and obscurus means 'dark' or 'dusky', so the name paints a picture of a dark, sharp-nosed shark and explains the common name 'dusky shark'.
