Land annelids, such as earthworms, obtain oxygen through their skin via a process called cutaneous respiration. Their skin is moist, allowing for the diffusion of oxygen from the environment into their body while simultaneously releasing carbon dioxide. This adaptation is crucial, as they do not have specialized respiratory organs like lungs or gills. For effective gas exchange, they require a moist environment to keep their skin wet.
No, they do not.
Aquatic annelids respire primarily through gills, which are specialized structures that extract oxygen from water. In contrast, land-dwelling annelids, such as earthworms, rely on cutaneous respiration, absorbing oxygen directly through their moist skin. This method requires a moist environment to facilitate gas exchange, as their skin must remain wet for effective respiration. Overall, the distinction lies in their adaptations to their respective environments—gills for aquatic life and skin for terrestrial habitats.
Depending on the density, there will be pockets of air, especially if the ground is really loose. Worms and some other annelids breathe through their skin., so they don't even have to stop.
