Europa's Subsurface Ocean Found to Contain Exactly One Very Large Fish

NASA's Europa Clipper has detected what mission scientists are describing with visible discomfort as 'a singular, continuous biological signature' beneath the ice shell of Jupiter's moon Europa — a single organism of approximately 900 kilometers in length that appears to be swimming in slow, deliberate circles. 'We expected microbial life,' said mission lead Dr. Cassandra Vey, staring at sonar readouts with an expression reporters described as 'haunted.' 'We did not expect a fish the size of France.' The organism, provisionally classified as Megapiscis europensis and nicknamed 'Kevin' by the operations team, was first detected as an anomalous sonar return during the Clipper's fourteenth orbital pass. Subsequent passes confirmed the signal as a single, moving biological mass with what appears to be a rudimentary skeletal structure and 'something that might be a face.' Dr. Vey emphasized that calling it a 'fish' is a dramatic oversimplification. 'It's not a fish. It's a subsurface aquatic megafauna of extraterrestrial origin that bears a superficial morphological resemblance to a fish. But yes, it looks exactly like a fish.' Kevin's existence raises profound questions for xenobiology, including how a single organism could sustain itself in a closed ecosystem, whether it reproduces, and whether it is aware of the spacecraft observing it. On the last point, data from the most recent flyby suggests Kevin may have looked up. 'The sonar signature shifted orientation toward the surface for approximately fourteen seconds during our pass,' Dr. Vey confirmed. 'We are choosing not to speculate about what that means.' The European Space Agency has proposed sending a submarine probe. Kevin has not consented.
