Morphology
family + Rajidae
This is a straightforward compositional noun phrase: 'family' (a taxonomic grouping) combined with a taxon name 'Rajidae' denotes the family called Rajidae. The meaning follows a regular, cross-linguistic pattern (family + taxon name) so a learner who knows 'family' and recognizes 'Rajidae' as a taxonomic label can infer it refers to the group of skates.
Etymology
The name family Rajidae comes from the old word raja for a sea fish called a 'skate' and the family ending -idae used to name groups of related animals. So it literally means the 'family of skates', which is why we use it for these bottom-dwelling fish.
