Massive Swarm of Eels Is The Most Fish Ever Recorded at The Bottom of The Ocean

CARLY CASSELLA

Before we start mining for precious metals in the darkness of the deep sea, we might try switching on the light first and observing our surroundings.

In this seemingly isolated abyss, at deeper than 3,000 metres (9,800 ft) below sea level, scientists were able to coax a massive swarm of 115 cutthroat eels (Ilyophis arx) out of the shadows and into the light, and with only a relatively small package of bait.

The footage represents the greatest number of deep sea fish ever recorded at one time in the abyssal ocean, and it was shot right near an international mining hotspot.

“Our observations truly surprised us,” says biological oceanographer Astrid Leitner, who worked on the research at the University of Hawai’i at Mānoa. 

“We had never seen reports of such high numbers of fishes in the sparsely-populated, food-limited deep-sea.”

The Clarion-Clipperton Zone (CCZ) is a massive expanse of seafloor that runs from Hawaii nearly to Mexico, and it contains some of the rarest and most highly demanded metals and elements on our planet. 

Over the years, it’s drawn increasing interest from the mining industry, which sees this new region as a way to cut down on human labour and the destruction of precious land.

Sixteen contracts have already been issued for deep sea mining in more than 1 million square kilometres of this zone, and yet only a tiny portion of deep abyssal habitats have been sampled, explored, or even mapped by scientists.

It’s decisions like this that have some scientists and environmentalists warning of a deep sea “gold rush” that could cause unforeseen damage to ecosystems we know very little about…….More Here
