Animal · 2 hexes · SM +1 Giant Sea Horse [Monsters on Automatic, SRD coverage: mundane birds, fish and aquatic animals; answers Giant Sea Horse (SRD 5.1)]
Ridden by sea elves and sahuagin alike, and worth more than a good horse. It is armoured in bony rings, placid to the point of stubbornness, and slower than anything that wants to eat it — which is why it is a mount and not a hunter.

Notes
- GCS ancestry draft: gcs/giant-sea-horse.gct
- Independent build total: -39 points of racial traits plus 1 points of racial skills.
- Answers the SRD heading(s): Giant Sea Horse (SRD 5.1). Only the creature identity is taken from the SRD; the GURPS statistics, ratings and prose are this project's own work and reproduce no SRD text.
- Typical Stats, damage and ratings are derived from the racial template, not authored beside it, so the sheet and the stat block cannot disagree.
- Body mass used to scale this build: 180 kg. ST, Size Modifier and DR are checked against it; see the gurps-animal-sanity-check skill for the bands.
- Movement: ground Move 3; water Move 3 (primary). The published Move is the primary medium's cruising Move; sprint figures are stated here and not folded into it.
- Treasure and grappling are not authored for this batch and ship as explicit nulls; `lair` carries a short habitat note, because where a wandering animal dens is an encounter fact rather than a loot one.
- Three metres from crown to curled tail, which is the SM +1 row.
- ST is set by what a mount has to do: Basic Lift must carry an armed rider. That raised it from an earlier draft, where it had been scaled from mass and could not have borne one.
- Deliberately slow: Basic Move is bought down, because a sea horse's whole body plan trades speed for armour and station-keeping.
- Added after a post-hoc comparison against independent GURPS fan conversions of this creature: Peripheral Vision. The comparison surfaced the gap; the build is still ours.

- Description
- Written by Dungeons on Automatic, released under cc_by_4_0
- Independently authored GURPS build. The SRD supplies the creature identity this record answers to and nothing else: no SRD statistics, wording or presentation is reproduced, and no third-party GURPS conversion was used as an input.
- Answers the SRD heading(s): Giant Sea Horse (SRD 5.1).
- Racial template: -39 points across 17 traits, plus 1 racial skill(s) worth 1 points.
- Every trait is drawn from the project's controlled GURPS vocabulary in scripts/srd/trait-library.mjs, which carries the page reference and published cost for each entry.
- sourceSystem is recorded as doa_fixture because that is the package contract's value for project-authored material; the SRD headings this record answers are in provenance.coversSourceIdentities.
- Ratings are recomputed through the consumer CER path on every build, so a mechanics change cannot leave a stale rating behind.
