Question

Mention difference between animals living in surface water and animals living in deep sea?

Answer 1

Answer:

Organisms living in the deep ocean must survive in a physical environment that is radically different from ocean habitats near the sea surface. ... Light is virtually absent in the deep ocean, which means that deep-sea organisms cannot rely on vision for feeding, avoiding being eaten, or mating.

Explanation:

First off, the deep ocean is dark because sunlight can't penetrate very far into the water. Many animals make their own light, called bioluminescence, to communicate, find mates, scare predators, or attract prey. ... Most animals cope with this by being very small and needing less to eat or by growing very slowly.

Answer 2

The difference between animals living in surface water and animals living in the deep sea are as follows:

• The creatures living in deep have to survive in extremely severe conditions, such as hundreds of bars of pressure, low levels of oxygen, small amounts of food, no sunlight, and constant, extremely cold temperatures.
• Generally, these creatures have to depend on food floating down from above for their survival
• Deep sea creatures cannot survive on the surface water as there will be a pressure imbalance.
• The pressure inside their body would be as high as the pressure outside so that they can maintain pressure balance and easily survive
• If we bring fish from the bottom of the ocean and leave them in surface water, they would burst.

• Fishes that live closer to the surface of the ocean do have a swim bladder. A swim bladder is a large organ with air inside of it.
• This air helps them float up or sink down in the water.
• The animals living on the surface water do not face a lot of harsh situations, such as high air pressure, lack of sunlight, or low temperature which are faced by the animals living in deep water.
