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.
