Morphology
The phrase is a straightforward taxonomic label: 'subphylum' denotes a subdivision of a phylum and 'Urochorda' names the group of sac-like marine animals. A B1 learner who knows both constituent meanings can infer this refers to the subgroup of chordates that comprises Urochorda (tunicates), so the meaning is directly compositional.
Etymology
Subphylum Urochorda The name subphylum Urochorda comes from the parts uro meaning 'tail' and chorda meaning 'cord'. Tunicate larvae have a stiff 'cord' in their tail, so the name points to that feature and shows this group is a 'subgroup' of chordates.
