Morphology
The meaning is directly compositional: 'phylum' names a biological rank and 'Sipuncula' identifies the taxon (peanut worms), so the phrase simply denotes the phylum that contains those worms. This taxonomic naming pattern is regular in scientific language and cross-linguistically transparent, so a B1 learner who knows both constituents can infer the MWE meaning.
Etymology
Phylum Sipuncula probably gets its name from how these soft sea worms look when they pull their head inside; they become short and round like a little peanut, so people call them 'peanut worms'. That's why phylum Sipuncula refers to a group of soft, unsegmented sea worms with a head that can be pulled in.
