Final answer:
The types of fish have larger swim bladders (air bladders) is deep-sea fish like anglerfish and gulper eels
Step-by-step explanation:
The swim bladder is a gas-filled organ found in bony fishes that helps them control their buoyancy. It allows fish to adjust their position in the water column by changing the amount of gas in the bladder. While all bony fish have swim bladders, some species have larger swim bladders than others.
For example, deep-sea fish such as anglerfish and gulper eels have larger swim bladders to help them survive under high-pressure conditions in deep waters. The larger swim bladder allows them to maintain buoyancy despite the extreme water pressure.
In contrast, fish species that inhabit shallow waters or rivers, such as bass and trout, have relatively smaller swim bladders. They do not need as much buoyancy control in these environments, so their swim bladders are smaller compared to deep-sea species. So therefore deep-sea fish like anglerfish and gulper eels have larger swim bladders to survive under high-pressure conditions, while fish in shallow waters have smaller swim bladders.
