Fishing experts are looking for ways to fish in the mesopelagic zone, a layer of water that stretches from 200-1,000 meters (660-3,300 feet) beneath the surface, which has, thus far, remained ...

A new study offers the first direct evidence that deep-dwelling mesopelagic fish, which account for up to 94% of global fish biomass, excrete carbonate minerals at rates comparable to shallow-water ...

The ongoing decline in ocean oxygen levels is intensifying due to climate change, significantly impacting marine ecosystems, including mesopelagic fish populations. This could disrupt marine food webs ...

Oarfish can grow longer than 20 feet and normally live in a deep part of the ocean called the mesopelagic zone, where light cannot reach. A rarely seen deep sea fish resembling a serpent was found ...

Scientists have uncovered why big predators like sharks spend so much time in the ocean’s twilight zone. The answer lies with mid-sized fish such as the bigscale pomfret, which live deep during the ...

For decades, oceanographers have known that something did not add up in the deep sea. Huge predators like sharks and tunas were spending long stretches in the dim “twilight zone,” yet the known prey ...

Woods Hole Oceanographic Institution (WHOI) researchers have shown large sharks can spend hours deep in the oceans' mesopelagic zone, which lies 200 to 1,000 meters (650 to 3,300 feet) below the ...

New research sheds light on the overlooked contribution of the ocean’s most abundant fish to marine carbon cycling. The findings open new avenues for studying deep-sea carbon dynamics and may improve ...
