61. Setae draw water from mud: marsh crab
"Some species, including Sesarma, have an additional means of gaining water from the soil by what are, in effect, roots. Tufts of hydrophilic setae at the bases of the legs are brought into contact with the moist surface of the mud and can actuall...

62. Fine filaments filter water: peacock worm
"A feeding peacock worm…has a fan of radiating tentacles fringed with fine filaments to sieve food particles from the water currents." (Foy and Oxford Scientific Films 1982:25)
63. Skin protects from water loss: humans
"The vertebrate integument represents an evolutionary compromise between the needs for mechanical protection and those of sensing the environment and regulating the exchange of materials and energy. Fibrous keratins evolved as a means of strengthe...
64. Plants use molecular bonding to transport water.
Fluid transport through plant xylem and phloem occurs through cohesion (water molecules bonding to each other to form a chain), adhesion (water molecules hydrogen bonding with tube walls), and transpiration. Transpiration creates a pressure gradie...
65. Hairs prevent entry of water: rat-tailed maggot
"Some diptera (Syrphidae or red-tailed maggots [rat-tailed maggots]) and Ephydridae (shore flies) have a pair of posterior, telescopic breathing tubes that open in spiracles with hydrophobic hairs that prevent water from entering." (van der Valk 2...
66. Radiating filaments filter water: fanworms
"Increased surface area is extremely useful to many creatures…The radiating filaments of the fanworm filter the water for food particles: the more water is covered, the more food is found." (Foy and Oxford Scientific Films 1982:24)
67. Foot aids underwater movement: water snail
"A UC San Diego engineer has revealed a new mode of propulsion based on how water snails create ripples of slime to crawl upside down beneath the surface."Eric Lauga, an assistant professor of mechanical and aerospace engineering at the...

69. Leaves optimize photosynthesis: giant water-lily
"In still or slowly-moving waters there is one easy way to collect [light]: a plant can float its leaves upon the surface. No plant does this on a more spectacular scale or more aggressively than the giant Amazon water-lily. A leaf first appears o...
70. Underwater roots get oxygen: giant water-lily
"The Amazon water-lily is able to produce such large and strong structures because it can collect an abundance of food through its roots from the mud at the bottom of the lake. But roots need to breathe and the mud at the bottom of Amazonian swamp...
