Do dolphins snore when they sleep?

No, dolphins do not snore when they sleep. While dolphins do spend a significant portion of their time resting, they do not experience sleep in the same way that humans do. Dolphins engage in a unique sleep pattern called unihemispheric sleep, where they only sleep with one hemisphere of their brain at a time, allowing the other half to remain active and alert. This sleep pattern is necessary for dolphins to be able to breathe and monitor their surroundings continuously. As such, they do not produce the same sounds associated with snoring.
