Buoyancy Compensator

in what ways are fish bladders and buoyancy compensator vests similar?plzz help asap it's grade 8 science!!

as they fill or release air it will control where you are in the water. It is a lot harder for a fish, the fish have to get the air from their blood stream because they do not have lungs. Taking in air is harder because it is via their blood and they cannot release the air as fast as buoyancy compensator vests.

Include all of this information and you should do fine.

This information came from a marine biology professor.
