In my recent exploration of marine life, I've discovered that sharks indeed venture down to 3,000 feet below the ocean's surface! It's truly fascinating that these creatures are capable of thriving in such extreme conditions. However, not all shark species are found at these depths, with some preferring shallower waters. Predominantly, it's the deep-sea sharks that we find at these incredible depths. So, yes, while it's not common for all sharks, some do indeed make the deep-sea their home.
