What fish live in the depths of the ocean?

The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2\% of known marine species inhabit the pelagic environment.

What’s the deepest living fish?

The fish that currently holds the depth record is a species of cuskeel (family Ophidiidae) called Abyssobrotula galatheae. This 20 cm long fish has been collected from the Puerto Rico Trench at a depth of 8,370 m (27,455 feet).

What lives in Hadalpelagic zone?

Marine life decreases with depth, both in abundance and biomass, but there is a wide range of metazoan organisms in the hadal zone, mostly benthos, including fish, sea cucumber, bristle worms, bivalves, isopods, sea anemones, amphipods, copepods, decapod crustaceans and gastropods.

How deep can amphipods live?

Amphipods thrive below 8000 m, perhaps because there are no fish eating them. There are scavenger species that eat organic material from above, and predatory species that eat the scavengers.

What is in the deepest part of the ocean?

At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth. Challenger Deep is the deepest point of the Marianas Trench.

What is the deepest ocean depth?

approximately 36,200 feet
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep.

Where do Hadal snailfish live?

Northwest Pacific Ocean
Pseudoliparis amblystomopsis, or the hadal snailfish, is a species of snailfish from the hadal zone of the Northwest Pacific Ocean, including the Kuril–Kamchatka and Japan Trenches.

What fish lives in the Mariana Trench?

Mariana snailfish
In the Mariana Trench—7,000 meters below the ocean’s surface—these fish makes a living in total darkness and at crushing pressures that can reach 1,000 times more than at sea level. But the Mariana snailfish is not only abundant in this area; it’s the region’s top predator.

Where is the hadal zone located?

The hadal zone (separated from the bathyal by the even darker abyssal zone) starts at the ocean floor, around six kilometers below sea level. It consists only of trenches formed by the movements of the earth’s tectonic plates. At the deepest (in the Mariana trench) these stretch to 11km below sea level.

Is the hadal zone dark?

At depths of 3,000 to 6,000 metres (9,800 to 19,700 ft), this zone remains in perpetual darkness. It covers 83\% of the total area of the ocean and 60\% of Earth’s surface. The area below the abyssal zone is the sparsely inhabited hadal zone.

What is hadal amphipod?

Amphipods are tiny crustaceans that inhabit almost every marine ecosystem, from beaches to the deepest parts of the ocean, and that fill a wide range of ecological niches. As a result, they are used as a model organism in efforts to study how life has adapted to the trenches and elsewhere in the ocean.

How big is an amphipod?

around 2-3 cm long
Amphipods are a type of crustacean normally around 2-3 cm long. But the creatures discovered in the Kermadec Trench were more than ten times this size.

What animals live in the hadal zone of the ocean?

The most common organisms include jellyfish, viperfish, tube worms and sea cucumbers. The hadal zone can reach far below 6,000 meters (20,000 feet) deep; the deepest known extends to 10,911 meters (35,814 ft).

What kind of eyes does a Hadal amphipod have?

A hadal amphipod from 10,500 m the Sirena Deep collected on this expedition. Scale bar on left is in centimeters (cm). Close-up of head shows yellow patches that are thought to be rudimentary eyes, but the function of the red eye-like lobes is uncertain.

Can amphipods survive below 8000 m?

Dr Stuart Piertney and Chloe Weinstock retrieve water collected with the SOI Rock Grabber Lander from the Sirena Deep, 35,000 ft. SOI/ Paul Yancey Now consider those prey. Amphipods thrive below 8000 m, perhaps because there are no fish eating them.

Is the hadal zone the same as the abyssal zone?

Historically the hadal zone was not recognized as distinct from the abyssal zone, although the deepest sections were sometimes called “ultra-abyssal”.
