Thaliacea is a class of marine chordates within the subphylum Tunicata, comprising the salps, pyrosomes and doliolids. Unlike their benthic relatives the ascidians, from which they are believed to have emerged, thaliaceans are free-floating (pelagic) for their entire lifespan.W CalCOFI holds 8,390 observations of it in 2 datasets between 1951 and 2026, across 3 taxa under it.R
