Morphology
Delphinapterus + leucas
This is a Latin scientific binomial (taxonomic name) rather than a compositional English phrase; its referent 'beluga whale' is a specific species label that B1 learners cannot reliably derive from the parts. One constituent is undefined here and taxonomic epithets are essentially arbitrary to learners, so the overall meaning is not predictable from the constituent words.
Etymology
Delphinapterus leucas comes from Greek words and gives a clear picture: delphin- means 'dolphin', -apterus means 'without a fin', and leucas means 'white'. So the name literally says 'white, finless dolphin', which fits the beluga whale and helps you remember it is a white whale with no dorsal fin.
