71. Nanoparticles block UV light: English ivy
"The concern for the biosafety and health risk for the metal-based and engineered nanoparticles in sunscreens has led to the search for alternative replacement nanoparticles. In this study, naturally occurring ivy nanoparticles were investigated t...

72. Water absorbed from humid air: brown dog tick
"The ability to absorb water vapor from the atmosphere enables ticks to survive without drinking water for many months. The tick rehydrates using a three-stage process. First, it uses its foremost pair of legs to detect microregions of high humidi...
73. Eyes see above and below water surface: four-eyed fish
"Native to Caribbean lagoons, Anableps anableps is commonly known as the four-eyed fish because its two eyes are split by horizontal partitions into two halves, each of which has its own iris and retina. This unique optical construction lets the f...
74. Flexible stalk adjusts to flow forces: Styela sea squirt
"An equivalent scheme serves the same function in at least one tunicate or ascidian (fig. 7.3b), a sessile marine animal about as distantly related to a caddisfly as are we. These 'sea squirts' have the relevant plumbing inside themselves rather t...
75. Senses help navigate during migration: European eel
"Those specimens that do complete their life cycle use many environmental cues to navigate during their migration. Not only are eels highly sensitive to olfactory stimuli, they also respond readily to small fluctuations in water movements, seismic...
76. Bioinspired adhesive tape
Insects are well known for their ability to walk with ease on vertical surfaces, rough or smooth, and scientists have long been looking for ways to reproduce those abilities. A team of researchers from the Max Planck Institute joined with a team o...
77. Corky tuber stores water: Hottentot bread plant
"Swollen roots are used by a great number of plants as storage tanks. Beneath the sand, they are out of sight and not easily found by thirsty animals living on the surface. Hottentot bread is the name given to a yam that develops an immense underg...
78. Flexible cylinders siphon water: clams
"Cylinders may also act as pipelines carrying one material through another, like underground pipes. Man's oil or drainage pipelines are usually rigid, but in nature flexibility is more valuable for this purpose. Some bivalve molluscs, such as clam...
79. Sticky berries adhere: European mistletoe
"The only European mistletoe is the strange twin-leaved parasite that once played an important part in human fertility rites, perhaps because in winter its leaves remain green and visibly alive when those of the tree on which it grows have all fal...
80. Nest sheds water: tropical hornet
"The conical shape of the [nest of the] tropical hornet Vespa affinis leads rain water efficiently away from the nest." (Pallasmaa 1995:12)
