You are a marine researcher seeking to find and observe an array of aquatic life in the colorful Sunlight Zone, ghostly Twilight Zone, and pitch-black Midnight Zone of the world's seas and oceans. In Finspan, the fish you discover over four weeks will generate a series of benefits as you dive deeper into the ocean.

Each dive site specializes in a key aspect of expanding your research:

• Grow your collection of fish.
• Discover freshly laid eggs.
• Hatch eggs into young and consolidate young to form schools.

The winner is the player with the most points gained from fish, eggs, young, schools, and achievements.
