What are some facts about deep ocean waters?
The ocean is deep. In fact, most of it is deep. Officially anything deeper than just 200 metres is considered the “ deep sea ”, but the average depth of the entire ocean is about 3.5km and the deepest point – the Challenger Deep in the Mariana Trench, in the western Pacific – is a little short of 11km down.
What is unique about the deep sea?
The deep – sea is defined as the part of the ocean below 200 meters depth. This environment Is considered extremely harsh with temperatures of below 5 degrees Celsius, extreme pressure (2,000 meters equals about 200 times the atmospheric pressure at sea level), and no sunlight.
How long do deep sea fish live?
1), and some species can reach 200 years old . Cailliet et al.  suggest that great longevity could be facilitated by slow metabolism. In deep – sea fish, metabolic rates are typically an order of magnitude lower than in fish living near the surface .
Why do deep sea fish have eyes?
Musilova says having highly sensitive eyes may be useful for detecting the glowing bioluminescence emitted by many deep – sea creatures. These bioluminescent lights are mostly blue and green in colour. Being able to tell colours apart could help fish distinguish whether a flash comes a predator or prey, Musilova says.
What are 5 facts about the ocean?
These 10 unbelievable ocean facts illustrate just how important these initiatives are.
- Our oceans cover more than 70 per cent of the Earth’s surface.
- The majority of life on Earth is aquatic.
- Less than five per cent of the planet’s oceans have been explored.
- The world’s longest mountain chain is underwater.
What Colour is deep ocean?
Deep Ocean ® is a conservative yet appealing colour that mimics the richness and depth of the ocean, and the vast blue haze of a distant mountain range.
At what depth is the ocean dark?
It is sometimes referred to as the midnight zone or the dark zone. This zone extends from 1,000 meters (3,281 feet) down to 4,000 meters (13,124 feet). Here the only visible light is that produced by the creatures themselves. The water pressure at this depth is immense, reaching 5,850 pounds per square inch.
Why are deep sea creatures so big?
Large creatures that exist in the deep oceans normally depend on food that drops from above them. It means that there is scarce food at this level. Thus, these deep swimming animals are more efficient and therefore become larger.
Why are deep sea animals Red?
Red light is quickly filtered from water as depth increases and red light effectively never reaches the deep ocean. When struck by white light, a red fish at the surface reflects red light and absorbs all other colors and thus appears red.
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.
Why are deep sea fish not crushed by pressure?
Under pressure Fish living closer to the surface of the ocean may have a swim bladder – that’s a large organ with air in it, which helps them float up or sink down in the water. Deep sea fish don’t have these air sacs in their bodies, which means they don’t get crushed.
How many fish are in the ocean 2020?
The best estimates by scientists place the number of fish in the ocean at 3,500,000,000,000. Counting the number of fish is a daunting and near-impossible task. The number is also constantly changing due to factors such as predation, fishing, reproduction, and environmental state.
Can fish see humans?
Not only is a fish able to recognize a human face, complete with two eyes, a nose, and a mouth, but an archerfish is able to recognize a specific human face, able to detect and pick up the various details and nuances that make each individual appearance unique.
What do deep sea fish see?
Most deep sea fish are most sensitive to blue light. It makes a lot of sense. Bioluminescent light is mostly blue, so they need to see it for hunting, mating, and defence. As well, blue ambient light penetrates deeper into the ocean — that’s why underwater photographers use red filters when they start going deeper.
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.
