Morphology

Casmerodius + albus

This is a Latin binomial (genus + species). If a learner knew the specialized genus meaning (Casmerodius = a type of large egret) and recognised albus as ‘white’, they could reconstruct the referent, but those are technical/taxonomic items in Latin that most B1 learners will not know. Because part of the meaning is recoverable from the parts for learners with some biological/Latin knowledge but not for typical learners, the expression is only partially transparent.

Etymology

Casmerodius albus comes from two name parts: Casmerodius, an old word for a marsh heron, and albus, the Latin word for 'white'. So the name literally paints the image of a 'white marsh heron', which matches the large white egret we see today.
