It’s easy to forget that beneath the sunlit waves, just past where the ocean’s blue turns to jet-black, lies a world teeming ...

Scientists have revealed footage of a colossal squid swimming in the deep ocean. It's the first time we've seen one alive in ...

Imagine descending into the ocean’s deep, dark twilight zone, a realm straight out of science fiction. Here, in a place where ...

Also known as the midwater, or mesopelagic layer, the twilight zone stretches between 200 and 1,000 meters below the ocean's surface and is home to a huge variety of organisms that have adapted to ...

Octopuses are benthic or mesopelagic organisms that typically avoid open-water interactions with pelagic apex predators. Conversely, mako sharks, known for their streamlined morphology and ...

The twilight, or mesopelagic, zone — the layer of ocean water that extends 200–1000 meters (656–3280 feet) deep — is an inhospitable place. “It’s completely dark, it’s extremely cold ...

Microplastics (MPs) are particles with a diameter of <5 mm. The disposal of plastic waste into the environment poses a significant and pressing issue concern globally. Growing worry has been expressed ...

The twilight zone is an important depth of the ocean where particulate organic matter (POM) remineralization takes place, and prokaryotes contribute to more than 70% of the estimated remineralization.

The microbialization of coral reefs predicts that microbial oxygen consumption will cause reef deoxygenation. Here we tested this hypothesis by analyzing reef microbial and primary producer oxygen ...

These populations can be separated into five communities: Arctic, Antarctic, temperate and tropical epipelagic (up to 200 m below the surface), mesopelagic (200 to 1,000 m below the surface), and ...
