You may wonder, do beluga whales sleep vertically? Sleeping position
Most sleeping whales stay in a horizontal or vertical position close to the surface or at the surface. Resting at the surface is called “logging” because the motionless, floating body of a whale has an uncanny resemblance to a drifting log. Some species sleep at greater depths.
Similarly one may ask, where do belugas sleep? Other species such as the fin whale swim slowly and quite close to the surface, partially emerging their bodies at regular intervals to breath. In captivity, belugas have also been seen resting at the bottom of the pool.
Besides above, how long do beluga whales sleep for? Whales can sleep for a maxim of 15 to 30 minutes at a stretch. However, they sleep in phases and can nap during different hours of the day. On average, whales sleep for about 7% of their day, with the exception of beluga whales, who can sleep for up to 30% of their day.
Likewise, how do whales breathe while sleeping? Whales choose to come up to the surface to breath in the same way that we make a conscious decision to eat so that we don't starve! Unlike humans who continue to breath even when they're in a deep sleep, cetaceans must remain partially awake in order to maintain a state of alertness to control their breathing.
