Conservation
The common bottlenose dolphin is an important predator in coastal and open-ocean ecosystems, helping keep fish populations balanced and serving as an indicator of overall ocean health. While not globally endangered, many populations are threatened by pollution, entanglement in fishing gear, habitat degradation, boat strikes, and noise pollution from shipping and sonar. Conservation efforts focus on marine protected areas, fishing-gear regulations, pollution reduction, and long-term monitoring to ensure dolphin populations remain stable and oceans stay healthy.
