15 FAQs ( Frequently Asked Questions)

  1. Just how deep is the ‘deep ocean’ anyway?

    The “deep ocean” starts at the twilight zone, about 200 meters (656 feet) below the surface. Here, sunlight fades, and the environment becomes much colder and darker than the surface waters.

  2. Why is the deep ocean so dark?

    Sunlight cannot penetrate far beneath the ocean’s surface. By the time you reach the deep ocean, almost all sunlight has been absorbed, leaving these depths in perpetual darkness.

  3. What kind of creatures live in such a harsh environment?

    Many amazing creatures are uniquely adapted to the extreme pressures, cold temperatures, and lack of light in the deep sea. We find bizarre anglerfish with bioluminescent lures, see-through jellyfish, giant squid, and otherworldly-looking fish and invertebrates.

  4. How do deep-sea creatures find food in the darkness?

    Many deep-sea creatures rely on senses other than sight to find prey. Some have highly sensitive eyes adapted to detect faint bioluminescent light. Others have enhanced senses of smell or use echolocation to locate food and navigate the abyss.

  5. Are there really underwater volcanoes?

    Absolutely! Hydrothermal vents are like underwater volcanoes found along the ocean floor’s mid-ocean ridges. These vents spew superhot, mineral-rich water and support entire ecosystems independent of sunlight.
