Do any fish live in the middle 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.
Which part of the ocean has the most living things?
The epipelagic zone extends from the surface to 200m down. It receives plenty of sunlight and therefore contains the most biodiversity in the ocean.
Are fish at the bottom of the ocean blind?
Many deep-sea creatures are thought to be blind. Some have developed gargantuan eyes. Others detect subtle movements in the water by changes in pressure. And you may be familiar with the anglerfish, which uses a fishing pole atop its head to dangle a bioluminescent “lure” that other sea creatures see, at their peril.
Which ocean has the largest fish?

What are the characteristics of different types of fish?
Certain body characteristics are more common in particular environments. Fishes that live in clear and sunny coral reefs are noticeably different from those that live in muddy rivers. Reef fishes tend to be brightly-colored while those that live in murky water tend to be mud-colored.
What differentiates the layers of the ocean?
In fact, sections of the water column in the ocean are differentiated by pressure, light, temperature, oxygen and mineral nutrients. It is because of these elements that certain sections of the ocean only contain certain marine animals. In this blog, we will explore the layers of the ocean and what types of marine life resides in those layers.
How many species of animals live in the ocean?
Given the vast size of the ocean, it is impossible to know the exact number of species that live there. Research suggests, however, that the number of species in the ocean is decreasing.
What animals live in the bottom of the ocean?
The water temperature here is near freezing, at 32 degrees Fahrenheit and there is no light at all. Very few creatures can be found at these crushing depths. These creatures are invertebrates like basket star fish and tiny squid. Seventy-five percent of the ocean floor lies in this zone.
