* Location: Oceanographic conditions like water temperature, salinity, and prey distribution influence their depth range.
* Individual: Some orcas may be more comfortable diving deeper than others.
* Behavior: Orcas may dive deep to hunt, for instance, but spend much of their time closer to the surface.
General Estimates:
* Average depth: Most orcas stay within the top 1,000 feet (300 meters) of the ocean.
* Deepest recorded dive: The deepest dive ever recorded for a killer whale was 900 meters (almost 3,000 feet).
It's important to note that these are just estimates, and our knowledge of orca diving behavior is still evolving.
