Arctic Sedge Slider

Arctic Sedge Sliders are massive organisms, bipeds standing 10 meters tall and adapted to life in the cold environs of their homeworld, Darwin IV. Their name originates from the furrows they leave in their wake. As a way to survive the cold, they utilize a specialized adaptation whenever the temperature drops or a fierce arctic storm approaches along the horizon: they can retract their head deep into the warm body cavity, only extending it again once conditions have become favorable once again to resume their stalled activities. Their species is notable for having what may be the biggest sonar bulge of any fauna on Darwin IV. This massive organ of theirs produce sonar pings in not one but multiple frequencies. Also, as this bulge is situated on their back, it gives the species the ability to "see" in 360º, which makes it far more difficult for a would-be predator to catch one of their kind by surprise.
