VIVA – So far, many people think that fish are one of the animals that never sleep. But as it turns out, fish are not animals that never sleep in their daily. 

For many animals, sleep becomes the most important process of restoring several functions in the animal's body, characterized by changes in the state of consciousness, reduced animal responses to external and surrounding stimuli, and the process of regulating homeostatic conditions in the animal's body.

Therefore, animals can know when it's time for them to sleep. But unlike the following animals that are predicted never sleep.

This happy-go-lucky marine mammal does not need to sleep for some time. Newborn bottlenose dolphins (Tursiops truncates) do not sleep for the first month of their lives. The reason for this is simple: they have to resurface for air every 3 to 30 seconds.

Trying to get some shut-eye in between those bursts would take the term "micro-nap" to a whole new level. And during this extended period of wakefulness, their mothers will also stay alert to steer the ship and keep a close watch on their precious young. This same protocol has also been observed amongst killer whales.
