“Snailfish” Deepest-ever fish discovered at 8 km. under the sea

Life around us isn’t always limited to the sky, earth, or even just the surface of the water, and people from Friday Harbor Laboratories, such as Mackenzie Gerringer, have helped us realize so!

Welcome to the world of wispy, ghostly, purple, and pinkish-white animals from 22,965 ft (7000 m) and below the ethereal snailfish.

Discovered for the first time at the Pacific Ocean’s Mariana Trench, this species is making headlines for its capabilities to endure and adapt to the extremely harsh conditions of living under high water pressure zones.

These species are endemic and appear in abundant numbers in the Mariana Trench.

They lay eggs that are unusually large, almost a centimeter wide. Scientists hauled up based on individual dissection that these snailfish never fall short of food.

These fishes often have pink, purple, or blue colors with flesh so translucent that even its liver could be seen from the outside!

A fish that’s so attractive at such depths is a sight to see. Moreover, they have no big teeth, no scales, which is quite out of the blue for a fish, and aren’t bioluminescent, which in layman’s terms means no emission or production of light by a living organism.

This is in contrast to jellyfish, which glow in the waters. They also have transparent and delicate fins and bodies that look gelatinous.

At first glance, their appearance may deceive you and make the animal look incapable of surviving the enormous pressure, but this is what makes nature a mystery, with such enigmatic animals existing and thriving in the environment’s harshest conditions with just such simple features.

The Mariana snailfish is about 2.0 in (5 cm), found in places like the Mariana Trench, Atacama Trench, and the Pacific Ocean.

These specialist species feed on a variety of items to sustain their bodies. These creatures feed on a mix of small and large copepods, plankton, and amphipods.

The adults also consume additional polychaetes and cumaceans. In fact, these snailfish specimens have about twenty-eight food categories to choose from!

Scientists claim this new species of fish to be one of the deepest living fish to be found from the ocean floor.

It is found at nearly 7966 m (26135 ft) in the Mariana Trench and in the dark, frigid ocean regions, also known as the Hadal Zone.

Hence these new species of snailfish are also called Hadal snailfish.

Due to the depths, they live in the sea; their habitat is a high-pressure environment with high water pressure.

These Mariana snailfish have various reproductive strategies.

Some snailfish are known to deposit their eggs in stones, cold-water corals, kelp, or even xenophyophores.

At times the male species guards this egg mass as well. After the eggs hatch, they rapidly reach the adult stage.

Are they dangerous?

To date, not much is known about how this species of one of the deepest fish on the planet is harmful or dangerous to humans or animals.

Although considering the fact that researchers like Gerringer and Alan Jamieson have analyzed the depths of its living to be approximately 22,965 ft (7000 m), it’s unlikely that these creatures would appear on the surface and harm anyone.
