Morphology

suborder + Petromyzoniformes

The phrase is directly compositional: 'suborder' denotes a taxonomic rank and 'Petromyzoniformes' names the group (lampreys), so a learner who knows both constituents can infer it refers to the suborder containing lampreys. This follows standard biological naming conventions and is therefore transparent, even though the taxon name itself is specialized vocabulary.

Etymology

Suborder Petromyzoniformes comes from old Greek words that mean 'rock' (petra) and 'to suck' (myzon). The picture is simple: lampreys use a round, sucking mouth to cling to rocks or other fish, so the name came to mean the group of 'lamprey' fish without jaws today.
