Bullfrogs do not sleep. They do not sleep because they do not have a need for "rebound energy".
Dolphins don't sleep with their whole brain simultaneously. The need to leave half awake to deal with breathing.
A lot of animals (like dolphins) are able to put one half of their brain to sleep, then put the other half of their brain to sleep at other times. The whole brain gets sleep, but the animals are able to stay functional 24 hours a day.
Some sharks are known to apprently never sleep.
However, tests have indicated that some sharks and rays are possibly able to swim while technically unconscious.
This only complicates being able to answer whether some swimming sharks may be doing so in their sleep. However, so far, it is believed that many sharks do not sleep.
All animals sleep, just not in the traditional thinking of the word. Many animals just enter a suspended animation period where there metabolic rates drop. Some types of animals are more easily identified as entering R.E.M. sleep, such as mammals, than others. Some types actually become more responsive in this resting period, such as certain types of toads/frogs, being close to the bottom of the food chain, while others become less responsive. Some types of animals, such as birds, can suspend this need for rest for longer periods of time, such as when in migratory routes. Whatever the definition, all animals do enter some sort of sleep or sleep-like inactivity.

An animal that sleeps during the day and is active at night is called nocturnal. Examples include most rodents, most bats, and the big cats. An animal that is most active around dawn or dusk is crepuscular.
it depends on what animal you are talking about because nocturnal animals sleep in the day and hunt in the night and some don't sleep at all.
They sleep, for only ten minutes at a time, and they do have eyelids so they can close there eyes, its just so qwick you dont see it.
Some factors influencing an animal's adaptation to a nocturnal lifestyle include temperature and predation. Firstly, in hot areas, animals may choose to come out at night to avoid strong heat from the sun during the day and to minimize water lost through sweating and evapouration (especially in dry climates). Secondly, animals may choose to come out at night in order to evade predators that hunt under daylight. Also, in special cases, animals could be nocturnal because the food that they eat are most abundantly available at night.
Nocturnal animals are animals that sleep during the day and are active at night. Different types of nocturnal animals include bats, hedgehogs and raccoons.
== == Animals that SLEEP at night (and are awake in the DAY) are called DIURNAL. Animals that are awake at night and sleep during the day are NOCTURNAL. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------
Animals who sleep during the day and are awake at night are called nocturnals.
some animals hunt food and others sleep. other animals hunt at night and sleep in the DAY
Animals sleep in trees and it depends on what type of animal it is.
Diurnal animals such as mockingbirds and squirrels sleep at night. Nocturnal animals such as owls and bats sleep during the day.
