Hubris is populated by thousands of strange creatures, all of whom have followed a very different evolutionary path to those on Earth. Instead of ears, eyes, nose, etc, the creatures on Hubris experience their world through the sensory crest on their heads, which combines all their senses together. Additionally, the vast majority of creatures here are filter-feeders, with rows of gills down their necks to catch the tiny micro-organisms that enrich the winds constantly blowing around the planet. However some, like the Tisgul, have evolved to hunt larger creatures, and their filter gills have changed to large, gaping jaws.
