Skyray

Skyrays are a group of cartilaginous fish part of the Batoidea superorder. They and their close relatives, the sharks and aquatic rays, comprise the subclass Elasmobranchii. Skyrays are among the largest group of cartilaginous fishes, along with aquatic rays, with well over 600 species in 26 families. Skyrays are distinguished from aquatic rays by having lungs (unlike most fish), gills being useless for breathing (and instead is used to help the skyrays fly), and slightly larger intelligence due to competition for food with other sky animals such as birds, despite this, all flying animals (including skyrays) are currently thriving.
