8.7 million species. One of them is reading this.
Pick a place to start.
Each one is a complete answer to the same question: what does life do when conditions change?
The lungs of the planet. Ten percent of all known life on Earth, packed into one drainage basin.
Where life evolved against the cold. Fat, fur, and patience as survival strategy.
The original arena. Where most of vertebrate evolution played its loudest hand.
Earth's largest habitat. Pressure measured in tons. Almost everything down here glows.
The cities of the ocean. 25% of marine species live here, on 0.1% of the seafloor.
The world's roof. Where animals evolved to breathe air thinner than altitude sickness.
The animals that came before. Bigger, stranger, mostly extinct, occasionally still here.
The one animal that lives in all of them. Soft skin, no claws, conquered the planet.
Where the forest walks into the sea. Roots breathe air, fish climb trees, the tide rules everything.
Where water is currency. Every animal here is a water-budgeting machine.
Earth's kidneys. Half-water half-land, double the species density of either.
Frozen ground, ninety-day summers. Life on a deadline.
No sunlight, ever. Eyes go blind, pigment vanishes, life invents new senses.
Less than 1% of Earth's water — and 10% of all known species.
The new biome humans built. Coyotes ride subways, rats outvote citizens, raccoons run for office.
Four seasons, deep memory. Trees here talk through fungal networks older than civilization.
The taiga. Largest land biome on Earth — endless spruce, snow, and silence.
The flat empire. Built grazing mammals, shaped human civilization, fed half the world.
Above the trees, below the snow. Short summers, intense colour, animals that won't go lower.
Underwater forests that grow 60 cm a day. Sea otters, sharks, and the only ecosystem rivalling rainforests for productivity.
Five Mediterranean climates, one playbook: drought-built shrubs, fire-loving plants, ridiculous biodiversity.
Life without sun. Tube worms, white crabs, and 400 °C chimneys on the seafloor.
Where evolution gets weird in private. Giants, dwarves, flightless birds, and species that exist nowhere else.
Slow water, hanging moss, alligators in the cypress shadows. Older than the dinosaurs that drowned in them.
When you're done learning, watch them fight.
Apex Clash. Real biology, real stats. Pick two animals. Science gives the verdict. The crowd votes anyway.
