swim-bladder

They developed into a fish-like animal with a very large swim-bladder to compensate for the rather higher density of the silicone tissues, and from these fish the land animals developed.

The part which, I think, will have most influence is when he gives whole series of cases, like that of whalebone, in which we cannot explain the gradational steps; but such cases have no weight on my mind -- if a few fish were extinct, who on earth would have ventured even to conjecture that lung had originated in swim-bladder?

Turbot, plaice, and other flat-fish, which have no swim-bladder, lie with one side in the mud at the bottom of the sea or rivers -- Can you guess in which side of the head their eyes are placed?

Nerve and muscle, special expanse of circling bones, swim-bladder and its tenuous gas -- all these combined to produce the aquatic harmony.

His whole being throbbed with the continuous deep drumming as the thin, silky walls of his swim-bladder vibrated in the depths of his body.

Again, an organ may become rudimentary for its proper purpose, and be used for a distinct one: in certain fishes the swim-bladder seems to be rudimentary for its proper function of giving buoyancy, but has become converted into a nascent breathing organ or lung.

For instance, a swim-bladder has _apparently_ been converted into an air-breathing lung. -- p. 181.

_I can indeed hardly doubt_ that all vertebrate animals having true lungs have descended by ordinary generation from the ancient prototype, of which we know nothing, furnished with a floating apparatus or swim-bladder -- p. 191.
