The Frogs of Titan
The Economist magazine said that some Nasa scientists were mumbling about chunks of ice floating by in the liquid methane. None of the scientists wanted to speculate publicly, but that's understandable for scientists in general, ever since they were beaten down for perpetrating the evolution hoax on the public.
Or, maybe the moving white specks are just JPEG compression artifacts. But since we may never know for sure, my vote goes for TITANIC (TITANIAN?) FROGS!!!
Here's an image showing a frog hopping (see arrow):
