It is marketed for use in hospitals and other places with a relatively high potential for bacteria to spread and cause infections. [1] The inspiration for Sharklet's texture came through analysis of the texture of shark skin, which does not attract barnacles or other biofouling, unlike ship hulls and other smooth surfaces. The texture was later ...
Notable examples of these natural structures include: honeycomb structure of the beehive, strength of spider silks, bird flight mechanics, and shark skin water repellency. [2] The etymological roots of the neologism "biomimetic" derive from Greek, since bios means "life" and mimetikos means "imitative". [citation needed]
Smooth skin: dolphins have little tear drops in their skin which traps some water so water flows over the water that is trapped. The skin feels soft and flaky and sheds every two hours.

It can then precipitate or melt to become liquid water again. All marine life is immersed in water, the matrix and womb of life itself. [7]
Doctors say they hope to reattach a young surfer's shark-bitten leg after it washed ashore. The 23-year-old was attacked at around 11 a.m. one morning as he tried to fight off the animal.
Nurse sharks are an important species for shark research. [3] They are robust and able to tolerate capture, handling, and tagging extremely well. [4] As inoffensive as nurse sharks may appear, they are ranked fourth in documented shark bites on humans, [5] likely due to incautious behavior by divers on account of the nurse shark's calm ...
A Galapagos shark off Kure Atoll in the Hawaiian Islands. The Galapagos shark is often the most abundant shark in shallow island waters. [7] In their original description of this species, Snodgrass and Heller noted that their schooner had taken "several hundred" adult Galapagos sharks and that "thousands" more could be seen in the water.
