Giant Shark - Dungeons on Automatic Bestiary

Animal · 5 hexes · SM +3 Giant Shark [Monsters on Automatic, SRD coverage: mundane birds, fish and aquatic animals; answers Giant Shark (SRD 5.1)]

Six metres of shark that has stopped treating boats as too large. It arrives from below and behind, takes one bite, and circles while whatever is left of the target bleeds. Skin like coarse rasp, no expression, and no reason at all to stop.

Notes

GCS ancestry draft: gcs/giant-shark.gct
Independent build total: 57 points of racial traits plus 8 points of racial skills.
Answers the SRD heading(s): Giant Shark (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: 1800 kg. ST, Size Modifier and DR are checked against it; see the gurps-animal-sanity-check skill for the bands.
Movement: ground Move 6; water Move 6, 12 at a sprint (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.
Six metres, which is the SM +3 row.
ST from Basic Lift: it carries off a 250 kg piece of whatever it bit.
Added after a post-hoc comparison against independent GURPS fan conversions of this creature: the Tracking skill, which a creature with Discriminatory Smell should always have. The comparison surfaced the gap; the build is still ours.

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 Shark (SRD 5.1).
Racial template: 57 points across 20 traits, plus 2 racial skill(s) worth 8 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.
