81. Compounds deter insect feeding: water smartweed
"Polygodial, a compound in Polygonum hydropiper (water smartweed) is among the most potent deterrents to insect feeding known. "The deterrent effect appears to be a direct result of the action of polygodial on taste receptors. In lepidopteran l...

Email82. Frogs store water in their bladder and under their skin.
"[T]he water-holding frogs of Australia actually store water in their bladder and under their skin for use during droughts." (Morell 2001)
83. Self-cleaning fabric
A patented self-cleaning fabric is undergoing a pilot trial at an Israeli factory. According to the website from the Laboratory of Polymer & Composite Materials, the laboratory "develops superhydrophobic interfaces, based on polymer ...
84. Gills filter food from water.
"In the warm waters of Australia's Great Barrier Reef, a giant clam feeds, its valves agape to filter water and extract the tiny living organisms from it." (Foy and Oxford Scientific Films 1982:113)
85. Hydrophilic polymers impede water movement by holding water inter- and extracellularly.
Hydrocolloids are large hydrophilic polymers frequently occurring in plants, especially seaweeds. All hydrocolloids interact with water, reducing its diffusion and stabilizing its presence. They play a critical role in seaweed by preventing dehydr...
86. Water changes physical properties of material, allowing material to absorb more water
"Note that the modulus of dry bast fibres is three to four times that of wet fibers. Water penetrates the amorphous regions and competes for potential hydrogen bonding sites and loosens the interactions between adjacent crystalline regions." (Wai...
87. Ear flaps keep water out: otters
"Among aquatic mammals such as the otter, the ear-flap can be pressed down to close the ear to water." (Foy and Oxford Scientific Films 1982:167)
88. Trees comb water from clouds: cloud forests
"Cloud forests, which are dense tracts of evergreens rising thousands of meters above sea level, contribute to yield, but in a novel manner: they literally comb water from the clouds. In the Cascade Mountains of Oregon and other coastal slopes or ...
89. Nasal surfaces remove water vapor.
"We have found that camels can reduce the water loss due to evaporation from the respiratory tract in two ways: (1) by decreasing the temperature of the exhaled air and (2) by removal of water vapour from this air, resulting in the exhalation of a...
90. Water strider legs stay dry.
“Water striders (Gerris remigis) have remarkable non-wetting legs that enable them to stand effortlessly and move quickly on water, a feature believed to be due to a surface-tension effect caused by secreted wax.(1–3) We show here, however, th...
