it's interesting that creatures of the land and air realms are so consistent in their appearance and body shapes and orientations. but when you go underground or into the deep ocean -- places well below the planet's surface and out of the reach of sunlight -- the animals appear so strange and physically exaggerated.
truly i'm a creature of the surface, so the creatures on my surface make sense to me and are familiar as such. but i just navigate upon basically a plane, and orient myself primarily with sight.
you get down in lightless regions of a spatial realm like the deep ocean, it must be the same as existing in outer space. there's no front or back to many of the creatures. if they have colors or markings, it doesn't matter, and many anyways are translucent. it sounds like such a relief.
