Titan’s underground ocean and what we’ll learn about ourselves by finding ETI

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Oddities in the rotation of Saturn's largest moon Titan might add to growing evidence that it harbors an underground ocean, researchers suggest. See article.
g Life - Over 100 million years ago, the understory of forests was dominated by plants from the class Equisetopsida. Now, only one genus from this once-diverse group survives. Now, scientists believe that the horsetail may be the oldest genus of land plant on Earth today. See article.
g Intelligence - Computer networks that can't forget fast enough can show symptoms of a kind of virtual schizophrenia, giving researchers further clues to the inner workings of schizophrenic brains, researchers have found. See article.
g Message - What are the chances that an alien signal has been sent our way just at the right moment to splash upon our antennas during that brief interval? If the extraterrestrials beam their broadcasts to the whole galaxy (or at least a big chunk of it), the chances are 100 percent. See article. This article is from 2007.
g Cosmicus - China's state-run news outlets report that preparations of the country's first space station module, called Tiangong-1, are in full swing for a launch in the second half of this year and will be followed by an unpiloted spacecraft. See article.
g Aftermath - Are we alone? Aliens on Earth from the Epicurean Greek philosophers more than 2000 years ago to fiction writers of the late 19th century, people have speculated about the possibility that there might be other worlds which are home to alien life. Yet it is only with the gigantic telescopes and interplanetary probes of the space age that we finally have a realistic hope of answering the question. As we learn more about our own planet and the evolutionary history of terrestrial life we feel a stronger urge than ever to put it into context. Embarking on the search for extraterrestrial life pushes our technology and scientific understanding to the limits, but the quest is one we should not shirk. Finding life beyond our own planet would teach us things about ourselves we might never otherwise learn. See article.

I've always wondered what sentient life from an underground/underice ocean would look like. I imagine that it would probably be something squidlike; as it wouldn't be a surfacing mammal (like our dolphins, etc), and it would probably need to be weak enough to develop sentience and tool-making, yet strong enough not to die out. I think some sort of squid creature would fit that bill pretty well.
