Explanation
This question is asking about how marine organisms are able to achieve nearly neutral buoyancy. We have a list of methods to select from, and one interesting option is "all of the above". Neutral buoyancy is the condition in which a physical body's average density is equal to the density of the fluid in which it is immersing. This enables the body to float without sinking or rising. Marine creatures utilize a variety of strategies to maintain neutral buoyancy - secreting gas into floats, storing oil, maintaining low-density body fluids, and also storing fat. Organisms could inflate or deflate the bladder with gas as they travel deeper or shallower, controlling their buoyancy. They make changes according to their environments.
