Gecko Feet

                                             Gecko Feet

               Geckos are known for their remarkably adhesive feet. In a study published Tuesday in the Journal of Applied Physics, researchers describe just how remarkable those feet are.

It turns out that gecko feet are able to stick and unstick themselves instantly -- so when a geck0 goes from hanging off of a ceiling to scurrying down a wall, it does so without losing speed or energy. This mechanism makes gecko feet, which were already being used as inspiration for wall-climbing robots and space-age adhesive materials, even more interesting to engineers.                                              

And also some gecko's can camouflage  when they step on diffrent colors like this

                     

Shark Skin

                                     SHARK SKIN

 Shark skin is smooth when you rub your hand one way but when u rub it in the oppisite direction because they have scales and those scales are for them to breath they don't breath through there nose like us.

The skin of the shark is unique in many ways. It is characterised by its grey colour and the contrast between its slippery appearance and its rough tactile texture.  

Dermal denticles are present on the shark’s skin and give it the rough texture that has earned it its primary human function as sandpaper. These are small structures that resemble hard, grooved teeth but are actually placoid scales.

They have a central pulp cavity, dentine and an outer layer of enamel. These strengthen and protect the skin of the shark against injury. They also aid in streamlining the fish while it glides through the water as they reduce turbulence. This is done by directing the water through the grooves and thereby decreasing the friction of the water against which the body travels.

TECHNOLOGY AS FRIEND OR FOE

                                             TECHNOLOGY AS FRIEND

TECHNOLOGY is my friend because you can go on social media and other websites.Sometimes robots could. save people lives someday maybe a robot will save your life.(FOE) Do you wish that some technology can do all your work but without your body working out. you will be fat and not very healthy you can also die for being to lazy in general people could just sit on the couch all day and send the robot to the store and some people just want to watch T.V. play video games all day.
