Hyotissa
genus of molluscs
Hyotissa is a genus of large saltwater oysters, marine bivalve mollusks in the family Gryphaeidae.
Species in this genus are known as honeycomb oysters, or "foam oysters" because under magnification, their shell structure is foam-like.

This brief starts where responsible research should: with the source description of “Hyotissa” as genus of molluscs. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of molluscs. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 20, 2025. The linked authority identifier is Q15151093. The first chronological checks are 1850, 1758, 1871 and 1985.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
