Suggested nameIsuberi Puna
Planet typeSmall cold gas planet
The water has probably photodissociated, and the free carbon dioxide has been swept into interplanetary space by the solar wind because of the lack of a methane layer.

The oceans are crawling with hostile interesting carnivores known to survive on the ground by hunting something called Tatyp Most Anono are related to the Doval-oh but have 2 arms and vary in length from 40 to 70 cm. Anono can endure temperatures from 80 to 160°C and extreme gravity which is common on this planet.
