Morphology

Agkistrodon + piscivorus

This is a scientific binomial (Latin) name made of technical taxonomic elements: one is a genus label and the other is a Latin-derived epithet not in the learner dictionary. An average B1 learner who 'knows' these constituent strings would not reliably infer the full meaning (a venomous semiaquatic snake called the cottonmouth); Latin roots like 'pisc-' may hint at fish-related meaning but taxonomic names and conventions are specialized and not transparently compositional for learners.

Etymology

Agkistrodon piscivorus comes from old Greek and Latin words: Agkistrodon means 'hook-tooth' (for its curved fangs) and piscivorus means 'fish-eating', because it lives by water and often eats fish. So the name is a simple picture of a water snake with hooked fangs that eats fish.
