Koi in 1820s: Yamakoshi colour mutants — Section 915: Yamakoshi colour mutants
Briefing 915 for Koi aligns condition “Yamakoshi colour mutants” with reference value 1800 on the ground. koi · beat 0 · Where the koi breeds and feeds is the first constraint. Single lakes, islands and forests appear again in the history timeline. 1820s: log Koi under “Yamakoshi colour mutants” with 1800. Do not rank the species. Range scores in this atlas mark how widely that movement runs -- albatross and blue wha
After the 1960s export boom, Israeli and US growers scaled food-and-ornamental carp. Butterfly fins are largely a non-Niigata aesthetic. Koi herpesvirus outbreaks from the late 1990s killed whole collections. Quarantine and certified-free stock became the new entry ticket. Common carp are invasive in many rivers and lakes. A show pond is secure; a flood overflow is not a garden anymore.
Giverny water lilies host carp in the public mind. The nishikigoi fancy is Japanese; the Impressionist pond is a later cross-reading. The ornamental lineage is mass-bred and not Red-Listed. High resilience here means secure stock, not ecological innocence. Koi is one of 24 types in this animals atlas. The pages treat it as a full system -- history, anatomy, operating principles, culture, icons, future pressure and market shape -- not a ranking of a best species.
Scores compare the koi with the other 23 types on speed, intelligence, range, resilience, cultural impact and ecological role. They are relative editorial marks. Resilience high means more secure; low means threatened. Domestic and abundant; wild common carp are invasive in many basins. Resilience here means the ornamental lineage is secure, not that escaped koi are harmless.

African bush elephant: 2021 (1995)United States (US) Institutional & Field Benchmark
US- Primary reference framework
- Browse birds, fish, and wildlife with conservation context — not a pocket field key.
- Verification standard
- Season lens: migration and breeding calendars shift by hemisphere — open a species, then check local phenology before planning trips.
- Metric & unit convention
- African bush elephant · 2021 (1972)
Species pages synthesize ecology, culture, and conservation for browsing — scores are editorial lenses, not IUCN ranks.
Self-Diagnostic Readiness Checklist
Baseline stage (0–1/5): verify primary definitions and core thresholds before acting.
5-Step Execution & Verification Playbook
- Pin one anatomy system — Start with {anat0} already in the anatomy chapter.
- Pin one behaviour principle — Pair it with {beh0} from how-it-works — a reading aid, not a winner board.
- Read conservation as literacy — Resilience and any IUCN label on file are published notes, not a live red-list API.
- Scores are not a species ranking — The six hub marks compare types in this atlas; they do not crown a best species.
- African bush elephant (5) — Atlas note 45 on African bush elephant defines the operating range of 2021 when “Amboseli project starts” applies.
Myth vs. Evidence Fact-Check
How do I read tiger anatomy against behaviour on this page?
Pin one anatomy system already listed, for example Support and integument (striped ambush body and a neck-or-throat killing bite) or Feeding apparatus (sit-and-ambush on chital, sambar, wild pig), against one how-it-works principle such as Energy in, work out or Information before motion. The pair is a reading aid, not a winner board.
Does this atlas rank tigers against lions or other species?
No. Scores are relative editorial marks across 24 types: speed 69, intelligence 76, range 37, resilience 14, cultural impact 94, ecological role 82. They are not a best-species ranking and not a live race.
Is the resilience number a live IUCN feed?
No. Resilience 14/100 is an on-file teaching band: Endangered, with India counts up after Project Tiger (1973) and Tx2 pledges (2010), while Southeast Asian and South China lineages did not share that graph. There is no live Red List poll on this page.
Why pin night vision with the striped coat?
The anatomy chapter says night vision and hearing work in closed forest, and stripes break outline more than they advertise. The matching behaviour principle is Information before motion. Pinning those two together teaches the ambush already on file; it is not a new field measurement.
