Why does the orca whale eat dolphins?

Orca whales, or killer whales, eat dolphins primarily due to their role as apex predators and their diverse diet. Different orca pods have unique hunting techniques and preferences, often targeting dolphins for their high-fat content and nutritional value. Additionally, dolphins can be more agile and challenging to catch, which may provide a stimulating hunting experience for orcas. This predatory behavior is a natural part of the orca's ecological role in maintaining marine balance.
