What to watch
Click an organism to inspect its genome, energy, age, generation, and current behavior. Body size, leg length, antenna length, shell or horn prominence, and color tint all come from inherited traits.

Genes and bodies
Each animal carries numeric genes for size, speed, sensor range, efficiency, fertility, armor, aggression, nocturnal preference, shore affinity, and color drift. Offspring copy the parent genome with Gaussian mutation and occasional larger jumps, so visible silhouettes drift quickly.
Behavior model
Mossbacks graze high-resource cells and flee nearby hunters. Nightstalkers sense prey, chase harder after dusk, and kill on contact after a short attack. Tidepickers seek carrion first, feed along the shoreline otherwise, and fertilize cells they visit.
Resources and pressure
Terrain height, moisture, and nutrients set plant growth. Grazers deplete patches, scavengers convert deaths into nutrients, and predators turn prey abundance into future predator births. Population caps keep the browser responsive while still allowing overshoot, crashes, and extinctions.
Day and night
Light, fog, sky, water, and behavior all change through a short day cycle. Plants regrow fastest in daylight, nocturnal hunters gain night sensor and movement bonuses, and prey lose visibility after dark.
