Baleine bleue 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: Baleine bleue
Baleine bleue is not a single postcard animal. It is a set of populations, subspecies and human rules inside the wildlife 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 Baleine bleue. 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 rorqual with ventral pleats, a 3 m heart in the public myth (the real heart is smaller than the postcard), and baleen for krill. Size is a filter-feeding outcome.
Lunge-feeding on krill swarms -- the most expensive gulp, paid by the densest food. Fasting between polar summer and low-latitude winter.
Culture and meaning
English-language culture met the Baleine bleue 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
Endangered. Some populations (California) are healthier; Antarctic blue whales remain a fraction of pre-whaling biomass.
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: Baleine bleue
Baleine bleue 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 rorqual with ventral pleats, a 3 m heart in the public myth (the real heart is smaller than the postcard), and baleen for krill. Size is a filter-feeding outcome.
Load paths and tissues (not metals) are expanded in the anatomy chapter.
Energy and foraging
Lunge-feeding on krill swarms -- the most expensive gulp, paid by the densest food. Fasting between polar summer and low-latitude winter.
The how-it-works diagrams reduce that budget to a six-node loop.
Senses and control
Low-frequency sound that crosses basins. Eyes are secondary in that budget.
Control here means the animal steering itself -- not a vehicle ECU.
Limits
A 1966 lock on a emptied south, and ships on the healthier coasts. EN is still the species card.
Resilience scores encode those limits relative to the other 23 types.
