Morphology
family + Testudinidae
The phrase structure 'family + [taxon name]' transparently signals a taxonomic grouping, so a learner who knows the word 'family' will understand this refers to a named biological family. However, 'Testudinidae' is a specialized proper taxon name (not decomposable into common English morphemes), so identifying that it denotes tortoises requires prior lexical or world knowledge of the name. Because the syntactic/compositional relation is clear but the referent of the name is opaque without exposure, the item is semi-transparent.
Etymology
Family Testudinidae comes from the old Latin word testudo, which means 'tortoise'. People used that word to make the scientific family name for land tortoises with domed shells and stumpy legs, so today family Testudinidae refers to that group of land-dwelling 'tortoise' species.
