cockroaches can survive underwater, but not for long since they need oxygen they get from air, not water, to live.

Cockroaches need oygen. They breathe through a system of tubes called tracheae, a word similar to the name of the tube leading to our lungs. The tracheae of insects are attached to the spiracles which are small valved openings on the side of each body segment, excluding the head. Thus the cockroach can breathe without its head! The valves open when the CO2 level in the insect rises to an unacceptable level; then the CO2 diffuses out of the tracheae to the outside and fresh oxygen diffuses in. The tracheal system brings the air directly to cells because they branch continually like a tree until their finest divisions tracheoles are associated with each cell allowing gaseous oxygen to disolve in the cytoplasm lying across the fine cuticle lining of the tracheole. CO2 diffuses out of the cell into the tracheole.âº

Cockroaches do need oxygen. "The cockroach is also one of the hardiest insects on the planet, capable of living for a month without food. It can also hold its breath for 45 minutes and has the ability to slow down its heart rate."

They need oxygen just like (almost) every other living creature on this planet.
There are only some bacteria that can survive without oxygen.
