What is another word for mesopelagic zone?
Pronunciation: [mˌɛsə͡ʊplˈad͡ʒɪk zˈə͡ʊn] (IPA) 
The mesopelagic zone, also known as the twilight zone, is an area of the ocean where sunlight does not directly penetrate, causing the water to be dimly lit. Other synonyms for the mesopelagic zone include the midwater zone, the middle ocean layer, and the deep scattering layer. The zone contains a diverse range of marine life, including small planktonic organisms and larger predatory fish such as lanternfish. Due to the depth and darkness of the mesopelagic zone, it remains largely unexplored by humans. However, scientists are beginning to study the region more closely, discovering new species and learning more about the vital role this zone plays in the oceanic ecosystem.
