Morphology

Eschrichtius + robustus

The name is compositionally a genus + specific epithet, so a learner who knows 'Eschrichtius' (a genus of baleen whales) and the Latin root 'robustus' could infer it denotes a particular whale species (literally a 'robust' Eschrichtius). However, the taxonomic Latin epithet is not standard English and does not directly give the common name 'gray whale', so the meaning is only partially predictable to a B1 learner.

Etymology

Eschrichtius robustus may come from a scientist called Eschricht and the old word robustus, which means 'strong' or 'sturdy'. So imagine a sturdy whale named after Eschricht, and that image helps you remember Eschrichtius robustus is the 'gray whale', a medium-sized whale found in the northern Pacific.
