Morphology

phylum + Platyhelminthes

This is a straightforward taxonomic noun phrase: 'phylum' plus the proper taxonomic name 'Platyhelminthes', so a learner who knows both constituents will understand it as the phylum called Platyhelminthes (i.e. flatworms). The construction follows regular naming patterns ("rank + name") and is non-idiomatic, so the meaning is directly derivable from the parts.

Etymology

Phylum Platyhelminthes comes from Greek words platy meaning 'flat' and helminth meaning 'worm', so the name literally says 'flat worms'. Today the word names the group of soft, simple animals like planarians and tapeworms that have a flat body.
