Roter Thun ist eine der 24 Arten in diesem Atlas. Kein Katalog: Evolution, Anatomie, Verhalten, Kultur, Ikonen, Schutz und Areal sind ein System.
Scores vergleichen Tempo, Intelligenz, Areal, Resilienz, kulturellen Einfluss und ökologische Rolle. Redaktionelle Relativwerte, kein Laborranking.
Sieben Kapitel graben nach: Ursprünge, Körper und Sinne, Leben und Verhalten, Kultur, Ikonen, Schutzdruck und das mit Menschen geteilte Areal.
Tiefe Einführung
Deep dive: Roter Thun
Roter Thun is not a single postcard animal. It is a set of populations, subspecies and human rules inside the fish family of this atlas.
Vielfalt, Körper, Kultur und Areale — plus eine Linse für diese Sprachregion.
Diversity inside the type
Field guides collapse many lineages into the English word Roter Thun. Subspecies, flyways and captive lines do not share one fate -- bald eagles and Philippine eagles, or western and mountain gorillas, are the caution.
This atlas picks a Wikipedia title as the hero image and then keeps the rest of the grade in view so a recovered stock cannot launder a CR cousin.
Life in the landscape
A fusiform thunnid with retractable fins and a keel. Rete mirabile keep swimming muscle warm; the heart is built for a high-output cruise.
Schooling forage fish and squid, taken at speed. Fat deposited for a sashimi market is the same fat that funds a transatlantic spawn.
Culture and meaning
English-language culture met the Roter Thun through film, law, heraldry and zoos. Those portrayals move money and sometimes take; they are not a field census.
The culture chapter dates posters and statutes so a 1975 film or a 1961 logo cannot pretend to be a 2020s Red List.
Conservation and money
Atlantic bluefin was a textbook overfish; some stocks rose after 2010s quotas while Pacific bluefin remained a separate tight ledger.
Tourism, conflict payments, quotas and captive loans are dated economic bands in the market chapter -- not live prices and not a best-species prize.

Biology deep dive: Roter Thun
Roter Thun biology is a stack of structure, energy, sensing and hard limits. The four sections below are the same headings used across the atlas so types can be compared without a best-species frame.
Anatomie, Sinne, Verhalten und Grenzen — plus Feldsprach dieser Region.
Structure
A fusiform thunnid with retractable fins and a keel. Rete mirabile keep swimming muscle warm; the heart is built for a high-output cruise.
Load paths and tissues (not metals) are expanded in the anatomy chapter.
Energy and foraging
Schooling forage fish and squid, taken at speed. Fat deposited for a sashimi market is the same fat that funds a transatlantic spawn.
The how-it-works diagrams reduce that budget to a six-node loop.
Senses and control
Vision in clear pelagic light and a lateral line for school chaos. Heat in the eye and brain is part of the thunnid hunting kit.
Control here means the animal steering itself -- not a vehicle ECU.
Limits
A price per kilogram that outruns patrol boats. Slow rebuilding if a year-class is seined for cages.
Resilience scores encode those limits relative to the other 23 types.
