NeuraQuarium simulates a basic aquatic environment populated by AI creatures. Watch them evolve and change through chance, or take a hand in their evolution by molding the environment.

Evolution in Action

The first creatures that spawn will have the same basic physiology and random neural nets. Those that succeed in finding enough food to survive and reproduce will pass down slightly different versions of their physical traits and brain structures. Over many generations, their offspring may come to be quite different.

Powered by Neural Networks

Each creature's behaviors are entirely determined by its artificial neural network. Not just decisions -- ALL behavior. There is no magic code telling a critter to "move toward" something, or telling it whether an object is food or an obstacle or another critter. Their vision is based on the colors, sizes, and proximity of objects within the visual field. Their motor neurons simply control their "muscles." If they learn to turn toward food or away from walls, or to pursue any other complex behavior, that's evolved, not coded.

You can watch the neurons fire in real-time, and see how brain structures are passed from parent to offspring.

Save your Favorites

Save copies of creatures who've evolved interesting behaviors or features with the click of a button, and just as easily, spawn in a copy at any time. Create a custom-curated ecosystem by mixing in your favorite species from past simulations.

Check out a few examples here.

Shape the Simulation

Easy-access sliders allow you to modify the parameters of the simulation, including mutation rates, the availability of food, and how costly it is to reproduce. You can modify the map with barriers to  separate environments or make mazes, or add food dispensers so that different areas have different availability of food.
