Morphology

Polycirrus = cirrus (semi-transparent) = poly + cirrus

The name appears to combine poly- 'many' with cirrus, but as a taxonomic genus label its meaning is only partly recoverable for most learners.

Etymology

Polycirrus comes from the parts poly- meaning 'many' and cirrus meaning 'curl' or 'fringe', like the 'cirrus clouds' that look thin and wispy. So the name helps you remember a group of marine worms with many small tentacles or fringes used to feed.
