CONFIRM_UNGROUNDED
Confirmed UNGROUNDED: no ontology term fits this concept. Nearest broader term ENVO:01001002 'animal-associated environment' attached as a parent. Ascidians as host. BTO:0000090 is a biological-source term rather than a habitat; treated as the other host clades are, parented to animal-associated environment. ENVO term request.

DEFINED
Defined as 'ascidian-associated environment' under ENVO:01001002 'animal-associated environment'. Definition curated from the committed deep-research report. The aquatic-invertebrate class is a tighter existing genus than animal-associated environment; the GOLD Tunicates > Ascidians hierarchy preserves the broader tunicate-associated HabitatMech parent. Genus moved from ENVO:01001176 'environment associated with an aquatic invertebrate' to ENVO:01001002 (#210), with the whole aquatic-invertebrate host family rather than record by record - #210 was filed over three records and the genus is actually held by five, so fixing only the three would have rebuilt the same split it reports. Both terms are true of the concept, so this chooses between two true genera on what each drags in: ENVO asserts ENVO:01001176 under ENVO:01001002 AND ENVO:01001055 'environment associated with an animal part or small animal', so the tighter genus makes every descendant inherit a size-and-partonomy restriction that is false of a whole adult sponge, ascidian, oyster, giant clam or sea urchin. ENVO's own modelling is the decisive evidence: ENVO:01001179 'cnidarian-associated environment' - the closest analogue, a taxon-scoped class over aquatic invertebrates - is asserted under ENVO:01001002 ALONE, and ENVO:01001176 has no children in the slice at all. Not carried as an xref: it is genuinely broader, so recording it would re-import the ancestry this declines.
