In "The Hydrogen Sonata" by Iain M. Banks, a vivid depiction of the natural world showcases the dance of birds and airfish as they navigate the skies and seas. Their presence is so prolific that they can obscure the sun, creating a breathtaking spectacle. These creatures gracefully glide above the ocean, occasionally dipping their wings to skim the surface before submerging into the depths below, emphasizing their connection to both the sky and the sea.

The imagery captures the harmony and beauty of these beings in motion, as they form intricate patterns against the clouds, resembling grey shadows. This portrayal reflects not only the elegance of nature but also the larger themes of the book, hinting at the coexistence of life within different realms, merging the architectural wonders of the atmosphere with the fluidity of the ocean below.
