Morphology

Opsanus + tau

This is a Latin binomial (scientific) name rather than a compositional English phrase; the constituents are proper-name elements not meaningful English words in learners' lexicons, so knowing them would not let a B1 learner infer 'oyster toadfish' or the fish's properties. Taxonomic names are language-neutral labels and are lexicalized, making the overall meaning unpredictable from the parts.

Etymology

Opsanus tau may come from old Greek words and the letter 'tau'. People call it the oyster toadfish because it looks like a fat toad with a wide mouth and often lives among oysters, so the name fits this slimy fish that lives on the sea floor.
