Blob fish are mostly made up of a gelatinous substance and have a density less than water so they can float above the sea floor without using too much energy as the water pressure is too high to move freely.

They live in deeps waters (600-1200m) with high pressures

They live in deeps waters (600-1200m) with high pressures so gas-chambered swim bladders are ineffective since the gases that help normal fish to control their buoyancy are too condensed at this level.
