in order to make up for his bad eyesight, manatees have super sensitive hairs, just like the super sensor, able to perceive the subtle move the nanoscale.

New scientist reports, larger animals, including man, is very clumsy and slow and noisy. Tolkien in describing the hobbit & other; In the face of large clumsy animals, just as you and I wait for the human, a huge noise, like an elephant often can be heard in a miles away, to fear from less & throughout; Said, summed up.

We tend to ignore the small things around the giant animals, but heavy Florida manatee is a special case of this law. Although it is much larger than a normal human body shape, but the small stream, it is capable of detecting moving objects even these tiny flow is nanometer level.

The first zha, manatees and is not a kind of biological skilled or elegant. It named after the deep like draft of seaweed, though they look more like a bloated or seals. Length of 3 meters, Atlantic waters off the coast of southern Florida manatee living in the United States and the gulf of Mexico. They are endangered species listed by the international union for conservation of nature: at present only less than 2500 species of wild adult. Due to the change of habitats and may hit the risk of ships, still faces the threat of a further decline in the species.

They cannot live with temperature below 20 degrees Celsius, so often live in shallow waters, the darkness of the mangroves and seaweed in the cold winter they tend toward the south or the upstream region of migration.

Gaspar DE found manatee can sense movement is very small, even to the nanometer level. Buffett is more sensitive than Hugh, can detect the movement of 0.9 nm.

For study the manatee biologist, they move to scientists has brought some problems. For such a heavy, they are very good at in full of obstacles, such as lodging trees waters navigation. & other; We don't understand how they are migrating, or how they do it so well, & throughout; The Sarasota DaMoTe Marine laboratory and aquarium joey & midd ot Watson sensor; Gaspar DE (JoeGcolowtemortalsdiscolourmenbitumend) said. & other; The speed of their short bursts to up to 30 km per hour, and completely will not affect the navigation to move forward. Throughout the &;

More let people confused, their vision is very poor, and freshwater dolphin is different, they do not have electrical sense or echolocation help them determine the azimuth. So gaspar DE doubt manatee or may have a very keen touch.

Therefore, gaspar DE for two manatee, buffett and Hugh, was tested. Since 1996, when their parents after being rescued in a toxic red tides, which has been living in captivity. Gaspar DE train them close to the water lever on the suspension of 6 cm wide sphere and let the ball slow vibration. If manatee can sense the vibration, they use their own contact a skateboard nose mouth, so you can get a piece of favorite food & mdhistriadn; & mdhistriadn; Apples, carrots, beets, and the monkey biscuit.


The super sensor

The results show that the manatee's hair, is very similar to the tentacles, will they become super sensor. When gaspar DE will net cover upon manatee, their sensitivity to slash. & other; The sense of touch is likely to be their primary sensory systems, & throughout; Gaspar DE said. & other; This is very unique in mammals in the world. Throughout the &;

Unfortunately, manatees delicate sense of touch and cannot help them escape in the face of one of the greatest threats: ships. Gaspar DE think their sensitive hairs can sense a few meters within the scope of the objects, so when they are able to perceive a ship speed, which is actually located above them.
