Embark on an oceanic adventure with "Orca and Marine Mammals" for iPhone. Take control of orcas, the ocean's top predators, to catch sharks that threaten the sea. Captured sharks can be fed in an aquarium, with rewards in points for your efforts. Engage in feeding sharks, earning points based on rarity and size, and aim to accumulate enough points to unlock various marine mammal friends and stunning background images.

In case of difficulty in catching sharks, use your finger to feed them and watch food replenish over time. Additionally, enjoy the augmented reality feature to swim with orcas in your own space, adding a unique touch to your gaming experience.
