Here's a breakdown:
* Most common depths: Dolphins are usually found in the upper layers of the ocean, typically within the first 100 meters (330 feet). This is where their prey is most abundant.
* Deeper dives: Some species, like deep-diving dolphins, can dive to much greater depths. The bottlenose dolphin, for example, has been recorded diving to around 300 meters (984 feet).
* Factors affecting depth: The depth a dolphin dives to depends on factors like species, prey availability, and the specific habitat.
So, while dolphins are often found in shallower waters, they can definitely dive deep when necessary.
