Do deep sea fish have swim bladders?

The lifecycle of deep – sea fish can be exclusively deep water although some species are born in shallower water and sink upon maturation. any organisms develop swim bladders (gas cavities) to stay afloat, but because of the high pressure of their environment, deep – sea fishes usually do not have this organ.

What happens to a fish if their swim bladder is ruptured?

When the swimbladder bursts, the swimbladder gases escape into the fish’s body cavity, where they can continue to expand. Venting releases these gases from the body cavity, thus eliminating the pressure on the internal organs.

Is it painful for a fish to be out of water?

Dr. Culum Brown of Macquarie University, who reviewed nearly 200 research papers on fish’s cognitive abilities and sensory perceptions, believes that the stress that fish experience when they’re pulled from the water into an environment in which they cannot breathe may even exceed that of a human drowning.
