Animal · 1 hex · SM +0 Reef Shark [Monsters on Automatic, SRD coverage: mundane birds, fish and aquatic animals; answers Reef Shark (SRD 5.1)]

Small as sharks go and rarely interested in anything person-sized, until several of them are and the water is already cloudy. Reef sharks hunt in loose company over coral, and what makes them dangerous is arithmetic rather than size.

Notes

  • GCS ancestry draft: gcs/reef-shark.gct
  • Independent build total: -56 points of racial traits plus 8 points of racial skills.
  • Answers the SRD heading(s): Reef 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: 60 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, 9 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.
  • About two metres, which is the SM 0 row.
  • ST from Basic Lift: 25 kg carried off, which is a bite's worth and no more.
  • 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.

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): Reef Shark (SRD 5.1).
  • Racial template: -56 points across 18 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.
