Morphology
Mergus + albellus
This is a Latin scientific name (binomial) rather than a compositional English phrase; the species meaning is not transparently built from everyday English words. 'Mergus' is a genus name and 'albellus' has no dictionary entry here, so a B1 learner who knows the listed constituents would not reliably infer that this refers to the smew, making the expression non-compositional for learners.
Etymology
Mergus albellus may come from old scientific words: Mergus for a diving duck and albellus meaning 'small white one'. So the name gives a clear picture of the tiny white duck called the 'smew', and that is why it refers to a small expert 'diver' on northern lakes.
