Morphology

Phocoena + sinus

This is a Linnaean binomial (scientific name) rather than a compositional English phrase; its referent (the vaquita) is a conventionally assigned taxonomic label that cannot be derived from ordinary word meanings. The constituents are technical/Latin (the genus name Phocoena and the Latin element sinus, which is not a transparent English lexical item here), so a B1 learner who knows everyday English words would not be able to infer the species meaning without specialized biological or taxonomic knowledge.

Etymology

The name Phocoena sinus may come from older words: Phocoena means porpoise and sinus means 'bay' or 'gulf'. So Phocoena sinus simply means a porpoise of the gulf, which explains why it is the vaquita found only in the Gulf of California and now critically endangered.
