What animals/insects hardly sleep in their lifetime

A Bullfrog never sleeps
a Elephant sleeps for 2 hours if you want a animal that does sleep but very little

Sleeping is mandatory for animals with brains because it rests the brain. When an animal is deprived of sleep, its brain's performance suffers, and the animal may even die due to lack of sleep. Some animals, such as sponges and jellyfish, have no brain. Therefore they do not require any sleep.
