What fullfills the orca's social needs in Zoo Tycoon 2?

In Zoo Tycoon 2, the orca's social needs are fulfilled by having at least one other orca in their exhibit, as they are social animals that thrive in groups. Additionally, providing a spacious and well-designed habitat with elements like water pools and enrichment items enhances their social interactions. Regular interaction with zookeepers and visitors can also contribute to their overall well-being.
