Deep sea animals take scientists back: “Only one in five species is known”

This is a good example of how deep the Pacific Ocean can go. It’s 36,161 feet under the surface.

The ocean ecosystem is still one of the most mysterious on Earth, giving scientists hope it could provide answers to many of science’s greatest questions.

A recent study on the Pacific Ocean, the largest and deepest ocean in the world — took three years to complete. Remotely operated vehicles (ROVs), which were remotely controlled captured nearly 350,000 images.

Only one fifth of the animals that were recorded had been identified as species.

This is a remarkable figure.

Scientists admitted that not all images could be identified, but most of the organisms were new to them.

Dr Scales stated that “When Rotjan’s group have completed analysing their findings, they will undoubtedly add entries to the World Register of Deep-Sea Species.” This list, which was updated in 2021, included 26,599 species. That number is on the rise.

They may be able to replicate 12 species discovered “hiding deep in the sea” in 2020.

Researchers warned, however that climate change could be a threat to the animal’s survival.

However, scientists agreed that it wasn’t too late for these species to be protected and their important habitats.

Researchers discovered 12 additional species, and 35 more records in regions previously unexplored.

Also, a field of hydrothermal vents were also discovered.

Ocean chemist Professor George Wolff from Liverpool was part of this project. He stated: “We still can say that we have better maps of Mars and the Moon than of the ocean floor.”

So, every time you visit the deep sea you discover something new. Not just species, but whole ecosystems.
