61. 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)

62. 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...

Hi its Teena here living in Netherland. I am a college student. My friends and I often spend our time together as we want to catch every moment of our life to have a fun. Weekend is the best gift for us. We start to wait for weekend from Monday mo...
64. 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...
65. 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...
66. Guard hairs repel water: reindeer
"Naturally, animals that live in polar regions have the warmest coats of all. The reindeer's coat combines long, water-repelling guard hairs with an extremely dense underfur, deep-piled like a shag carpet." (Foy and Oxford Scientific Films 1982:84)
67. Solar Water Still and Pump
Stephen Salter provides designs for a still and pump that works the way a tree transpires. Like a tree, it uses solar power to wick water up from underground, then captures the evaporated water. This water is purified--basically distilled--so can ...
68. Groasis waterboxx
Designed by Pieter Hoff, the Groasis waterboxx is a 20-inch by 10-inch box that serves as an incubator to help trees survive through the initial part of their growing cycle. The smartly designed container incubates one tree at a time, creating ide...
69. Networks share water: fungi
"Plant roots may be linked by shared or common mycorrhizal networks (CMNs) that constitute pathways for the transfer of resources among plants…Our results suggest that the movement of water by CMNs is potentially important to plant survival...
70. Leaves capture water: bromeliads
"So successful are these techniques for sending seeds up into the canopy that the massive branches of many forest trees are often densely lined with squatters. These are known as epiphytes and among the commonest are bromeliads. They anchor the...
