However, researchers are now copying the design of the snail when making small robots.
The razor clam has a long narrow shell, somewhat resembling an old-fashioned straight razor. The shells also have a sharp edge. The clam is hunted for food in exposed mudflats along the ocean shoreline. Its defense against people and predators is an impressive ability to burrow underground rapidly. They can dig downward at about one centimeter per second to a depth of 70 centimeters, or about 28 inches.

Long-finned pilot whales swim in cool regions of the oceans. They grow to 12-16 feet in length and weigh several tons. The whales are characterized by an enlarged forehead and a swimming behavior similar to dolphins. The creatures are found to have highly-specialized apparatus for maintaining smooth, clean skin. Countless tiny surface pores produce a slime coating. The gel washes off with movement and is continually replenished. This “skin care” prevents bacteria and algae from gaining a foothold and forming growth colonies. The whale’s surface chemicals also contain enzymes that repel microorganisms. This feature in turn avoids barnacles, tubeworms and other marine life which are otherwise attracted to underwater surfaces.
How can the production of “slime” by pilot whales possibly be useful as a technical application?

This example of a practical design in nature may lack appeal but it is vitally important to our health. A common phrase is to “lick one’s own wounds.” This saying expresses the effort to care for one’s own needs and generally look out for oneself. However, there is a more practical application. Dutch researchers are studying the chemical compounds in human saliva. They find an abundance of simple proteins called histatins that actively fight infection. Also present are compounds that cause epithelium skin cells to close quickly over a wound. Most of us have experienced the benefits of these saliva components. Small cuts inside the mouth tend to heal more rapidly than external injuries, and mouth healing leaves little scaring.
When it comes to sticking power under wet conditions, marine mussels are hard to beat. They can adhere to virtually all inorganic and organic surfaces, sustaining their tenacious bonds in saltwater, including turbulent tidal environments.
