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. [4] 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 ...
It is a colourless oil, although impure samples appear yellow. It was originally obtained from shark liver oil (hence its name, as Squalus is a genus of sharks). An estimated 12% of bodily squalene in humans is found in sebum. [5] Squalene has a role in topical skin lubrication and protection. [6]
Lipid-rich, collagen fiber-laced blubber comprises the hypodermis [2] and covers the whole body, except for parts of the appendages. It is strongly attached to the musculature and skeleton by highly organized, fan-shaped networks of tendons and ligaments, can comprise up to 50 per cent of the body mass of some marine mammals during some points in their lives, and can range from 5 cm (2 in ...
In vascular plants, the diploid sporophyte has evolved as the dominant and visible phase of the life cycle. In seed plants and some other groups of vascular plants the gametophyte phases are strongly reduced in size and contained within the pollen and ovules. The female gametophyte is entirely contained within the sporophyte's tissues, while ...
The entire body of a shark is a very efficient eating machine. Each organ has been fine-tuned for hunting and acquiring food. Sharks are built to feed: Here's why they are the ultimate eating machines
Photoprotection is the biochemical process that helps organisms cope with molecular damage caused by sunlight.Plants and other oxygenic phototrophs have developed a suite of photoprotective mechanisms to prevent photoinhibition and oxidative stress caused by excess or fluctuating light conditions.
