shoal
Let an agent explain shoals and how they form, describe their significance for navigation and ecology, identify specific shoals with sources, and support safe navigation questions.
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 shoals and how they form, describe their significance for navigation and ecology, identify specific shoals with sources, and support safe navigation questions.
A shallow area of sea, lake or river bed, often a submerged or partly exposed bank of sand, gravel or rock that rises near the surface, such as sandbanks, the Flemish Banks, baymouth bars and river mouth bars, and sometimes forming low islands; shoals are hazards to navigation, are charted and marked, shift with currents and storms, and support distinctive habitats and fisheries.
What it is for: Shallow banks under water.
It can be explain formation; describe navigation and ecology; identify specific shoals; support navigation questions.
Distinguishing features
Shallowness
Sediment or rock
Navigation hazard
Dynamic
What it looks like
Shallow water over a bank, sometimes exposed at low tide.
How it is recognised
Shallow bank rising near the surface
Sand, gravel or rock
A reef is rock or coral; a spit is attached to the shore; a school of fish is another sense
