How do deep sea fish eat?

Many bottom feeders get their nutrients from algae and other plant material. Others are carnivores and eat other bottom feeders. In the ocean, deep – sea bottom feeders eat jellyfish and squid, and in doing so, they absorb carbon dioxide—keeping it from going back into the atmosphere.
How do fish see in the deep sea?
Fish living in the deep ocean have evolved highly-sensitive eyes that can see a range of colour hues in the near-darkness. “They have more sensitive eyes and can see way better than humans in lower light.” Musilova and her colleagues collected DNA from 26 species of fish that live more than 200 metres below sea -level.
What do fish on the ocean floor eat?
Anglerfish are not very picky eaters, and as creatures that dwell near the ocean floor, they will try to find sustenance from any prey they encounter in a nutrient-poor environment. Any variety of crustaceans, snails, small fish, and even some prey up to twice the size of an anglerfish can serve as a possible meal.
Why do deep sea fish look scary?
The pressure at the bottom of the ocean is another factor in the weird appearance of the creatures there. The lack of available plant matter means that deep ocean animals must feed on each other or survive on decaying organic matter that filters down from the ocean above.
Can you eat deep sea fish?

What colors do fish see?
Water completely absorbs (or attenuates) different colors of light at different depths, affecting which colors are visible to a fish. Water attenuates red light from the spectrum first, oranges and yellows next, and blues and greens last ( see the chart below).
What colors do deep sea fish see?
Blue animals in the ocean live near the surface. Slightly deeper down, animals are blue on top and white on the bottom. At even greater depths, animals are generally transparent, but have red stomachs.
Do all fish eat other fish?
Fish are opportunistic, just like other living creatures. If food presents itself in any form, they will eat it. Other times it could be a more peaceful fish, but it’s also just as likely that it’s not another fish at all.
What eats a shark?
But some of the largest and most dangerous sharks such as great whites and tiger sharks will eat dolphins, porpoises, seals, sea lions, and other swimming mammals. As for shark predators, one thing that will eat a shark is another shark —with big sharks chowing down on littler ones.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. These periods of “suspended animation” may perform the same restorative functions as sleep does in people.
