34. Setae enhance temporary adhesion: leaf beetles

"Second, devices for intermittent adhesion in animals make extraordinary use of multiple contacts. The billion contacts of the gecko's feet may not be exceptional. Each of Stork's (1980) 5-microgram chrysomelid beetles had over ten thousand setae....

35. Sticky proteins serve as glue: green mussel

"The 3,4-dihydroxyphenyl-L-alanine (Dopa)-containing proteins of mussel byssus play a critical role in wet adhesion and have inspired versatile new synthetic strategies for adhesives and coatings. Apparently, however, not all mussel adhesive prote...
