What is the biggest zone in the ocean?
The next deepest zone is called the bathypelagic zone (or lower open ocean). This zone starts at the bottom of the mesopelagic and stretches down to 4000 m (13,000 feet). The bathypelagic is much larger than the mesopelagic and 15 times the size of the epipelagic. It is the largest ecosystem on earth.

Is swimming without goggles bad?
Swimming without protecting your eyes from the water can result in redness and irritation. The reason redness and irritation occurs is due to the pH levels in the pool. If the pH is too high, the chlorine in the water won’t be able to disinfect properly and keep both the pool and the water clean.
