Morphology

family + Hirudinidae

The phrase combines the general noun 'family' (a taxonomic grouping) with the taxon name 'Hirudinidae' (a group of leeches), so its meaning — the taxonomic family of Hirudinidae leeches — follows directly from the constituents. This compositional pattern (rank + scientific name) is standard in biology and cross-linguistically common, so a B1 learner who knows both words would understand it.

Etymology

Family Hirudinidae comes from the Latin word hirudo, which means 'leech'. Think of it as a family: a group of related leech species including the medicinal leech that share traits like making a substance that keeps blood flowing, so the name tells us this group is all true leeches.
