Blobfish

The blobfish’s famous droopy appearance is an artifact of being pulled up from the deep: at 600–1,200 m down, where pressure is dozens of times greater than at the surface, its gelatinous, slightly less dense-than-water body holds a normal fish shape. Up here, gravity makes it sag. That soft, buoyant body lets it hover just above the seafloor without spending energy swimming, snapping up whatever edible invertebrates drift within reach — a low-effort lifestyle perfectly suited to the food-poor deep sea.
