Morphology
The phrase is fully compositional: 'subphylum' denotes a taxonomic rank and 'Urochordata' names the group, so the meaning 'the subphylum called Urochordata (a group of tunicates)' follows directly from its parts. Taxonomic naming conventions are regular across languages, so a learner who knows both constituents can infer the MWE's meaning.
Etymology
Subphylum Urochordata comes from Greek roots uro- ('tail') and -chordata ('cord') because the free-swimming young have a tail with a cord-like support inside, and the word 'subphylum' shows they are a group under a larger animal group.
