The nasal surfaces of camels help conserve water by using hygroscopic properties to remove water from air during exhalation.

The leaves of ice plants store water in surface bladder-like cells.

The body of Texas horned lizards captures rainwater via splayed stance and interscalar channels on the skin.

The roots of desert plants extract hard to remove water from soil using negative pressure.

Trenches created by the flying saucer trench beetle collect water because the edges are above the sand surface and perpendicular to fog-bearing wind.

Floating mats of beaked sedge and other peatland plants aid survival in fluctuating water levels because they are held together and kept afloat by rootlike stems (rhizomes) of the plants.

The leaves of the Lady's mantle plant have a hydrophobic surface due to dense hairs.

The vein systems in some plant leaves are resilient to damage because they contain a high density of closed, interconnected loops.

Streams maintain aquatic organisms by maintaining natural hydrological regimes.

Wetland plants, bacteria, and the physical environment work together to remove particles and pollutants  

The leaves of Spanish moss absorb water and have slow water loss because they are covered in dense scales.

Lichens capture water via ice nucleation, absorbing the moisture once the temperature rises and the ice melts.

Peatlands regulate water flows because they lack topographic relief and well-defined channels, and have shallow water tables.

The Dufour's gland of plasterer bees protects their nests from water by secreting a natural polyester.

The skin of file snakes protects from dehydration because it is hygroscopic, absorbing moisture from the air.

The uropygial gland found in most birds protects them from water penetration, fungi, and bacteria by producing preen waxes.

Structures of flowers protect their pollen from rain by various physical structures.

Glandular openings for the red velvet mite provide waterproofing by a secretion that fills pores and congeals.
