Some stick to the coasts and shallow waters, and others prefer the deeper waters in tropical and subtropical waters. The most common shark species is the hammerhead shark, which can grow up to 12 feet long. The species has been known to grow to over 30 feet in length, making it the largest shark on the planet.

Is there any life in the middle of the ocean?
Many animals living in the deep ocean rely on dead animals falling from the surface to feed on. The deep sea is also home to a variety of creatures that live in a state of suspended animation. These creatures are called metazoans, and they can live for hundreds of millions of years. Some of these creatures, such as metazoan worms, are so long-lived that they are thought to be the oldest animals on Earth.
What fish can live in the deepest part of the ocean?
Meet the deepest fish in the ocean, a new species named the mariana snailfish by an international team of researchers that discovered it. The mariana snailfish can be found at depths of up to 8,000 meters (26,200 feet) along the united states’ pacific coast.
The discovery was made by researchers from the Woods Hole Oceanographic Institution (WHOI) and the National Oceanic and Atmospheric Administration (NOAA) in collaboration with the University of Hawaii at Manoa, the U.S. Geological Survey (USGS) Marine Mammal Program, and NOAA’s Pacific Marine Environmental Laboratory (PMEL). The research was published online today (March 16) by the journal Proceedings of National Academy of Sciences.
“”This is the first time we’ve ever found a species that lives at such a deep depth,” said WHOI marine ecologist and study co-author David R. Smith, who led the research team.
Can all fish swim to the bottom of the ocean?
A study suggests fish brains are too big to survive past a certain depth. The study, published in the Proceedings of the National Academy of Sciences (PNAS), suggests that deep-diving fish, such as tuna and swordfish, don’t have enough brain tissue to cope with the stress of being submerged for long periods of time.
The study was led by researchers from the Woods Hole Oceanographic Institution (WHOI) and the University of California, Santa Barbara (UCSB), and was funded by the U.S. National Science Foundation (NSF), the California Institute of Technology (Caltech), National Oceanic and Atmospheric Administration’s (NOAA) National Marine Fisheries Service (NMFS) Marine Mammal Stranding Network (MMN) Program, and NOAA’s Office of Marine Sanctuaries (OMS).
What ocean has no sharks?
They will generally avoid the cold waters. The areas with the greatest potential for sea level rise are the polar regions. Arctic is warming faster than the rest of the world, so it’s going to be more vulnerable to sea-level rise than any other place on the planet,” .
Is Point Nemo real?
Nemo didn’t technically exist until 1992 – or if it did, we didn’t realise it. Croatian-Canadian survey engineer used a computer program to figure it out. He didn’t even use technology to calculate the shape of the Earth’s surface.
In the early 1990s, the US Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA) teamed up to create the Global Positioning System (GPS) – a network of satellites that track the position of every object in the world. GPS system is still in use today, and is used by millions of people around the globe.
But it wasn’t until the mid-1990s that it was realised that the system could also be used to map the surface of our planet. This was thanks to the work of a Croatian geophysicist, who used the GPS data to construct a 3D model of Earth.
It was the first time that anyone had ever done this – and it proved to be a game-changer for the field of geophysics, which had been struggling with the problem of accurately mapping the surfaces of planets and moons for more than a century.
How deep is the bottom of the ocean?
The deepest part of the ocean is called the Challenger Deep and is located in the southern end of the Mariana Trench, which is hundreds of kilometers southwest of the U.S. territorial island of Guam. The deepest ocean trench on Earth is called Challenger Deep. The ocean floor at the bottom of this trench is covered with a thick layer of carbonate rock.
Carbonate is a mineral that forms when carbon dioxide is dissolved in seawater. The carbonates in this layer are made up of calcium, magnesium, and silica, all of which are common elements found in Earth’s crust and mantle. This image, taken by the European Space Agency’s Huygens probe, shows the seafloor near the South Pole.
Is there a dragon fish?
Dragonfish, also called sea moth, any of about five species of small marine fishes comprising the family Pegasidae and the order Pegasiformes. Dragonfish are found in warm Indo-Pacific waters. The fish are small and encased in rings. Dragonfish have a long, slender body and a short tail.
The body is covered in scales, which are made of keratin, the same substance that makes up fingernails and toenails. A dragonfish’s eyes are located on the top of its head, and its mouth is located in the middle of the body.
