oyster
Let an agent explain oysters as animals and food, relay biology, aquaculture, regional products and safety from marine and food sources, describe ecological roles, and distinguish edible oysters from pearl oysters, from other bivalves and from the registry aliases naming specific regional products.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain oysters as animals and food, relay biology, aquaculture, regional products and safety from marine and food sources, describe ecological roles, and distinguish edible oysters from pearl oysters, from other bivalves and from the registry aliases naming specific regional products.
A bivalve mollusc of the family Ostreidae and related families living in marine and brackish waters, harvested wild and farmed for food and pearls, with regional products such as Whitstable oysters in England, Hiroshima, Matoya and Uramura oysters in Japan and Gillardeau oysters in France, and farmed triploid oysters bred to be sterile and marketable year-round; oysters are filter feeders that build reefs and are important in aquaculture and coastal ecology.
What it is for: Food, pearls and reef ecology.
It can be explain biology and kinds; relay aquaculture and products; describe ecology and safety; distinguish related molluscs.
Distinguishing features

What it looks like
A rough irregular shell with a soft grey body inside.
Physical character
world production: about 6 million tonnes per year - mostly farmed
filtration rate: up to about 200 litres per day - per adult oyster
main species: Pacific, eastern, European flat list
How it is recognised
Reef-building bivalve harvested for food
Whitstable, Hiroshima, Matoya, Uramura and Gillardeau oysters; triploid oysters
Pearl oysters are a different family; mussels and clams are other bivalves

What the second pass must settle
- Should Pacific oyster and the regional products be separate primary entries?
- How should marine and food sources be linked?
- The registry entry has merged aliases naming regional products and a breeding type; should they be split off?
