Does the fish sleep?

Yes. They sleep and can sleep at any time of the day or night. Fish sleep with their eyes open because they do not have eyelids (except for some sharks) to close! At the surface level, many fish sometimes seem to be snooze. When snoozing, they respond less, their heart rate slowing and overall movement decreases. Some sleep during the day and only wake up at night, while others sleep at night and stay awake throughout the day. If you watch the fish for a long time, you will notice that they take breaks. They are in trance with their eyes open and seem to float in the place.

Why do they move when they are asleep?

Sometimes people look at fish when they are asleep and think they are awake because they are still moving. Most fish need to keep moving even during sleep so that they keep a constant flow of water through their gills to maintain the right amount of oxygen in their body. Some large fish, such as sharks, they swim at slow speeds while asleep. Small fish occasionally move their fins.

Does the fish dream while sleeping?

Fish do not dream when they are asleep because they do not have the neocortex, a part of the brain that helps us dream.

What will they do if they feel the danger?

Fish reduce their activity and metabolism, while being alert to danger. Some fish float in the area, some attach themselves to a safe place in the mud or coral, and some even find a suitable nest.

Do ostriches really bury their heads in the sand?

No. How can ostriches live if they bury their heads in the sand! This is just a myth.

Why did the myth arise?

This myth may have arisen from ostrich behaviours.

Ostriches are the largest and heaviest birds in the world. Despite being seven to nine feet tall and weighing 350 pounds, these birds have small heads. When they bring their heads close to the ground to eat grass, especially from a distance so they can be easily seen as if they were burying their heads in the sand.

Ostriches do not build nests for their eggs. Instead, they dig holes in the sand to keep their eggs. While the eggs are incubating, to ensure that the eggs are equally warm, male and female ostriches occasionally stick their heads in the nest to rotate the eggs, thus creating the illusion that they are burying their heads in the sand.

Similarly, ostriches will lie on the ground when threatened. Only their large bodies are visible from a distance, so some think the rest may have been buried.

How do ostriches escape from predators?

Ostriches are big, fierce and not afraid to take a stand against predators. When they feel the danger, their first response is to remove themselves from the situation with a quick clip.

An ostrich can run up to 40 miles per hour on its long, powerful legs. Instead of using their wings for flight, they are used as "air rudders" which helps them run—allowing them to zigzag, brake and turn quickly as they sprint away.

They can stand up against attackers. Ostriches can kick with a force of 140 kilograms per square centimetre - which is capable of killing a lion with a single blow.
