How does blobfish move?

A blobfish uses its fins to paddle and its tail to steer/change direction.

However...

Because the blobfish is a sea-bed fish which lives along the bottom of the sea beds where the pressure is so high, it is impossible for the gas bladder, found in most fish, to achieve perfect buoyancy. Therefore the blobfish evolved gelatine-like flesh which helps them to float in the extremely high pressures without using all of their energy.

A disadvantage of this is that the blobfish has relatively little muscles to help the fins and tails work properly. Therefore when blobfish hunt for food, they merely swallow edible things that simply float in front of it, rather than swimming around hunting food like most fish.

Blobfish are on the verge of extinction because of deep-sea trawler fishing.
