On left page there are two species of gecko-like aliens, with duplicated pectoral girdle. (more primitive Ullr land “vertebrates have one pectoral girdle, more advanced ones have two, so they have also four legs.
On right page thera are two species of flyers. Smaller one (sparrow-like omnivore) have eyespots on its wing membrane to scare predators when it opens its wings. And these eyespots imitate of course Ullr type eyes. The bigger one is Ullrian equivalent of stork. It walks (on four legs) and searches for small animals such as askewbugs.
