Morphology
The phrase is directly compositional: 'cetacean' names a group of marine mammals (whales, dolphins, porpoises) and 'species' denotes a taxonomic group, so together they mean 'species of cetaceans.' This noun-modifier pattern is a regular, cross-linguistic way to form compound noun phrases, so a B1 learner who knows both constituents would readily understand the MWE.
Etymology
Cetacean species comes from the word cetacean, which comes from the old word 'cetus' meaning 'whale', plus species, meaning 'kinds'. So it refers to whale-like sea mammals and today means all kinds of whales, dolphins and porpoises.
