Tide Room
A field room that appears only after the sea steps back.
Rarilo uses the word room because a tide pool has walls, thresholds, tenants, drafts, storage, and rules of entry. The room changes as the sun warms it and as water returns through cracks. A careful visit starts by reading the space before naming the life inside it. This page sets out the basic ledger used across Rarilo notes so observations stay comparable without becoming stiff.

01
Waterline
Note whether the pool is filling, draining, warming, or newly exposed. This changes what creatures risk showing themselves.
02
Shelter
Look under edges with your eyes only. Ledges, shell piles, and algae mats are rooms, not obstacles.
03
Motion
Record the first movement you see and the movement that appears only after waiting. Both matter.
04
Neighboring life
One animal is rarely the whole scene. Barnacles, wrack, sand fleas, birds, and shade all explain behavior.
The Rarilo test
If a note cannot say where the observer stood, what the tide was doing, and what remained uncertain, it is not ready. The test is simple because shoreline memory is unreliable. A field room deserves enough context that the next reader can understand both the claim and the restraint behind it.
