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]
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
This helps dolphins swim through the sea water at high speed. Shark skin: the surface of shark skin is covered with tiny 'teeth' or dermal denticles. The shape and positioning of these denticles varies across the shark's body, altering the flow of water in a way to minimize form drag. [5] Barracuda skin: Barracuda have hundreds of skin conduits ...
The shark kidney excretes urea that is needed for the shark to have in its system so the shark does not become dehydrated from living in seawater. [14] Sharks hearts have two chambers. The shark heart's main importance is providing oxygenated blood to the entire body while filtering out the deoxygenated blood. [ 15 ]
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.

It is one of the most abundant sharks ...
They use water, carbon dioxide, and sunlight to create their food. A layer of polysaccharides often forms over mats of cyanobacterial cells. [ 32 ] In modern microbial mats, debris from the surrounding habitat can become trapped within the polysaccharide layer, which can be cemented together by the calcium carbonate to grow thin laminations of ...
