Morphology

Thunnus + albacares

This is a Latin binomial scientific name (a conventional proper noun) rather than a compositional English phrase; its meaning 'yellowfin tuna' is a label established by taxonomy, not derivable from the constituents. The first element is a genus name and the second is an uninterpretable epithet (not a common English word), so a B1 learner who 'knows' those constituents would not be able to infer the species meaning.

Etymology

Thunnus albacares comes from words that name the fish itself: Thunnus is an old word for 'tuna' and albacares likely points to the fish's pale body and bright yellow fins. So the name paints the picture of a tuna with yellow fins, which is why it refers to the yellowfin tuna.
