The 'world's ugliest animal' only looks that way once it's out of the water
Blobfish live 600 to 1,200 metres down, where pressure is up to 120 times greater than at the surface. Their flesh is a gelatinous mass slightly less dense than water, letting them hover just above the seafloor without wasting energy swimming, since they lack the gas-filled swim bladder other fish use — one that would simply implode at that depth. Pulled to the surface, the sudden pressure change collapses their body into the sagging 'blob' shape people know from photos.
