Morphology
Petromyzoniformes = Petromyzon (opaque) = Petromyzon + iformes
This is a scientific taxonomic formation built from the genus name Petromyzon plus the order-forming suffix -iformes, but the resulting class name is not inferable for most learners.
Etymology
Petromyzoniformes breaks into Greek parts petro 'rock' and myzon 'to suck', while the ending -iformes marks a group of animals. So the name can be remembered as 'rock-suckers', which fits lampreys because of their round, sucking mouth and the way they cling to surfaces or hosts.
