Grand requin blanc est l’une des vingt-quatre espèces de cet atlas. Ce n’est pas un catalogue : évolution, anatomie, comportement, culture, icônes, conservation et aire forment un seul système.
Les scores comparent vitesse, intelligence, aire, résilience, impact culturel et rôle écologique. Ce sont des jugements éditoriaux relatifs, pas un classement de laboratoire.
Sept chapitres creusent : origines, corps et sens, vie et comportement, culture, icônes, pression de conservation et l’aire partagée avec les gens.
Introduction profonde
Deep dive: Grand requin blanc
Grand requin blanc is not a single postcard animal. It is a set of populations, subspecies and human rules inside the fish family of this atlas.
Diversité, corps, culture et aires — plus une lentille de cette région linguistique.
Diversity inside the type
Field guides collapse many lineages into the English word Grand requin blanc. 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 conical snout, serrated triangular teeth and a homocercal tail. Vascular rete keep core muscle warm; the liver is a vast oil store for buoyancy.
Ontogenetic shift from fish to pinnipeds where seals are dense. A single seal can fund days; scavenging whales is documented opportunistic income.
Culture and meaning
English-language culture met the Grand requin blanc 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
Vulnerable globally; Farallones, Gansbaai and Neptune Islands aggregations are better counted than oceanic juveniles.
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: Grand requin blanc
Grand requin blanc 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, sens, comportement et limites — plus le langage de terrain de cette région.
Structure
A conical snout, serrated triangular teeth and a homocercal tail. Vascular rete keep core muscle warm; the liver is a vast oil store for buoyancy.
Load paths and tissues (not metals) are expanded in the anatomy chapter.
Energy and foraging
Ontogenetic shift from fish to pinnipeds where seals are dense. A single seal can fund days; scavenging whales is documented opportunistic income.
The how-it-works diagrams reduce that budget to a six-node loop.
Senses and control
Ampullae of Lorenzini, a keen nose and rod-rich vision for a silhouette against the surface -- the classic seal-shaped cue.
Control here means the animal steering itself -- not a vehicle ECU.
Limits
Late maturity and few pups. Hooks, nets and a 1975 story are ceilings teeth cannot cut.
Resilience scores encode those limits relative to the other 23 types.
Warm swimming muscle -- a lamnid trick shared with makos and some tunas.
White Shark Cafe
Offshore Pacific aggregation between Hawaii and Baja where tagged whites linger.
Breach hunt
False Bay / Seal Island launches that made 2000s magazine stills.
OCEARCH
Public satellite-tag platform that turned individual whites into named tracks.
Jaws effect
Post-1975 spike in fear and some trophy killing -- later regretted by Peter Benchley.
CITES App. II
2004 listing for Carcharodon -- trade documentation, not a harvest ban.
Habitat and movement
Where the Grand requin blanc breeds and feeds is the first constraint. Single lakes, islands and forests appear again in the history timeline.
Range scores in this atlas mark how widely that movement runs -- albatross and blue whale high, koi and panda low -- not a quality ranking.
Research and law
Named projects (Project Tiger, ACAP, ICCAT, Amboseli) are the English-language bureaucracy of the type.
Listings and downlists are dated events in the timeline, not eternal essences.
Culture and price
Film, auction and logo years are filed under culture and market so they cannot masquerade as demography.
The icons chapter keeps eight real Wikipedia titles so a later language pack can attach the same faces.
