Spiders sub and fish in the air

Argyronetha is a spider that lives in the marsh and is able to catch air on the surface by forming bubbles that stick to his abdomen air. In this way he forms a big bubble and gets into it as a deep-sea diver getting into his diving suit. Therefore he has a silver colour. The mudskipper is a fish able to stay out of the water for short periods. In this way he survives to water evaporation in the ponds where he lives. By touching the ground with his robust fins he spends lots of time in the mud, with his body almost completely out of the water. In this way he can better catch the insects he eats.
