Vardan

Mooki's species are an unnamed aquatic mermaid-like species from Varda, who went extinct after their planet's oceans dried up. Their last member was a female scientist named Mooki.

Biology
Members of Mooki's species have humanoid upper halves that are externally indiscernible from Humans. However, their lower halves are large ichthyoid tails, giving them the appearance of mermaids. Members of Mooki's species can survive being out of the water for a certain period of time, but will eventually die if unable to reenter a body of water. Additionally, they are able to speak telepathically, even to robots.

Culture and society
Almost nothing is known about the society of this species. They were known to build underwater cities held up on columns some distance above the sea floor, and for moving on land, they utilized wheelchairs.
