much of this mistaken identity is due crassicornis & opalescens being merged together as a single species under H. crassicornis for about 90 years, but H. opalescens was reinstated as separate species in 2016
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!
