While sleep is essential for most animals, there are some unique species that either do not sleep or have very distinct sleep patterns than other animals. Here is the list of 5 animals that do not sleep or have different sleep patterns;

1 Jellyfish - These unique creatures do reach a state similar to sleep, with a significant reduction in pulsation and responsiveness to the surroundings.

2 Dolphins - Dolphins have a remarkable ability to rest one half of their brain while the other remains active. Newborn dolphins do not sleep for a month after birth.

3 Bullfrogs - Bullfrogs don't have a clear sleep-wake cycle. Instead, they enter a phase of inactivity, that may happen during the day or at night, depending on the temperature and humidity.

4 Fruit Flies - Fruit flies are extremely resistant to sleep, with some capable of living their entire lives without it. This has no effect on their general health or lifespan.

5 Giraffes - Giraffes are capable of staying awake for a full day without any kind of issue. They fall asleep, but just for 5 minutes.
