What are the blue dolphins natural predators?

Blue dolphins (Stenella coeruloalba) don't have any specific natural predators. They are one of the fastest dolphin species, capable of reaching speeds of up to 40 miles per hour, making them formidable opponents for potential predators.

However, like other dolphins and small whales, they can still be subject to occasional predation from larger marine animals such as killer whales (Orcinus orca) and sharks, especially when they are young, old, sick, or injured.
