As we all know, space is teeming with life, but as fictive astrobiologists, plausibilifying the exact nature of species is paramount. Hence, take into consideration these species and help me plausify their most noteworthy evolutionary capabilities.
For example, we already know (from the Greek) that Space Sperm Whales are best for precipitating panspermia. Space Frogs are well known to be best at making the jumps to and from hyperspace most efficiently. Space turtles are well suited to traveling to terrestrial planets with dense atmospheres, since their thermally insulated carapaces make them immune to excessive reentry temperatures.
So, with this in mind, help me flesh out exactly what any of my space creatures do better than any other creature:
Space Tube Worms
Space Lion Fish
Space Dolphins (Bottlenose and others)
Any other space sea creatures that would have distinctive, plot-worthy traits
