Why do creatures living in the twilight and midnight zones need to create their own light with bioluminescence?
sunlight doesnt penetrate that deep.
Why do deep sea fish have large eyes?
Down at those depths, there is very little light. Large eyes are able to channel and focus what little light there might be. Evolution have granted those deep sea living creatures with larger eyes over the time. At very deep depths, there is no sunlight at all. It is all filtered away by the water/ocean above. Still some organisms and even fish are able to make light. They often do this to attract prey, but can them selves become prey to those able to see.
Why cant deep water ecosystems rely on photosynthesis?
Because there is no light. Sunlight doesn't reach that far down.
What are sources for light?
Sunlight Moonlight (the reflection of sunlight off the moon) electricity fire starsbio-luminescence (fireflies, deep ocean creatures and glow-sticks) A baby's smile An angelic voice A first real kiss Dawn on new-fallen snow.
Can deep sea creatures see in the dark?
After just a few hundred metres there is very little light. Most deep sea creatures have very large eyes that can detect any light that is available. Even though there is virtually no light coming from the surface lots of deep sea creatures produce light through a process called bioluminescence. It is useful to be able to see this light as if you eat the light, you will be eating the creature that it is attached to. Unfortunately some creatures use these lights to draw in their own dinner!
Why is there no light in the midnight zone of the ocean?
Because it is so far deep only 1% of light gets through
Where are there ecosystems that do not rely on sunlight?
in caves and deep under the sea where light wont reach
Does the deep layer of the ocean get sunlight?
no because its to low that's why a lot of fish have a light to there head
Do the deep oceans have plants?
I would think not because sunlight can approximately reach down around 200 meters. The deep oceans are pitch black. There are no plants, but there still is life. There are bio luminescent creatures.
Fish that live in the very deep seas often produce their own to attract prey?
They produce their own light.
Where can creatures that can make their own light live?
They live deep deep under alot of water, at rock bottom, were the water is not blue it is a dark black color.
Creatures that use light producing features to lure prey?
The Gulper eel, Deep sea Angler, and lanterfish.
