if you look at the og's post, you can clearly see the orange tipped cerata
we get a lot of H. opalescens in Monterey & in this observation I made last year, you can see the white tipped cerata as well as the lack of white stripe on this individual: https://www.inaturalist.org/observations/223652802

vice versa, searches for H. opalescens shows images of crassicornis too! *confusing*
even on some university websites, they still incorrectly treat them as a single species
In recent years, the Hopkin's rose nudibranch & Spanish shawl had scientific name revisions too, so I get why this can make it feel confusing
plus, using tools like iNaturalist can take the pressure out of keeping track of taxonomic changes!
