Morphology

Trionyx + spiniferus

This is a Latin binomial (a scientific species name) rather than a compositional English phrase; the constituents are taxonomic labels (one of them is not even in the dictionary here), and their literal parts are not accessible to a B1 learner. Understanding that it denotes a particular river turtle requires specialized biological/Latin knowledge rather than knowing ordinary English words, so the meaning is not derivable from the parts.

Etymology

The name Trionyx spiniferus may come from old Greek and Latin words. Trionyx breaks into tri ('three') and onyx ('claw'), and spiniferus means 'spine-bearing', so the name gives the image of a 'three-clawed' turtle with small spines or bumps, which helps you remember this river turtle.
