How do mudskippers get oxygen?

Mudskippers obtain oxygen primarily through their skin and the lining of their mouth and throat, which allows for gas exchange when they are on land. They can absorb oxygen directly from the air when their skin is moist, making it essential for them to stay hydrated. Additionally, they have specialized gills that can extract oxygen from water when they are submerged. This unique adaptation enables them to thrive in both aquatic and terrestrial environments.
