Morphology
This is a straightforward taxonomic label: combining 'family' (a scientific grouping) with the proper name 'Squalidae' yields 'the taxonomic family called Squalidae.' There is no idiomatic or metaphorical shift and the construction is cross-linguistically common, so a B1 learner who knows the constituent words will understand the meaning.
Etymology
The noun family Squalidae comes from the Latin word squalus, meaning 'shark', and it names a group of small, spiny dogfish. These fish have a sharp spine in each of their two back fins, so the name now refers to this family of small, spiny sharks.
