Mosquito larvae, known as wrigglers, acquire air from the water surface primarily using specialized respiratory structures known as air tubes or siphons located at the end of their abdomens. When they need to breathe, the larvae rise to the surface of the water, where the siphons enable them to take in air without fully emerging from the water. This adaptation allows them to efficiently extract oxygen, which is critical for their survival in aquatic environments.

While it is true that certain aquatic organisms utilize gills for respiration, mosquito larvae do not possess gills, which makes this method of air acquisition incorrect for them. The method of moving to the surface periodically is part of their behavior but does not directly describe how they acquire air, focusing rather on their movement rather than the mechanics of respiration. Absorbing oxygen through their skin is a method used by some aquatic organisms, but it is not the primary means by which mosquito larvae obtain the air they need, emphasizing the significance of their specialized air tubes or siphons in respiration.
