(From the publisher):
In Ocean Under the Ice, the human explorers of the Barnard Star system and their large, friendly, amoebae-like alien friends, the "flouwen," explore an Europa-like moon about the gas-giant Gargantua. They find two bizarre life forms, one living on the ice, and one living in the ocean under the ice, that are as different and yet as related as butterflies and caterpillars.
