It was discovered by a German scientists that were using Google Earth to analyze herding patterns and behavior.]]> 2019-11-08 15:42:45 UTC https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/408702961 ning_sang41 https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/408828513

When baby sea turtles hatched they use the reflected moonlight to travel from their nest to the ocean but after hundreds of kilometer they use earth's magnetism to bring them back to their birthplace.]]> 2019-11-11 15:13:41 UTC https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/409498110 ning_sang41 https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/409505158 Sharks can detect electric and magnetic field in the ocean because they have special sensing organs called ampullae of Lorenzini that helps them. This ampullae is jelly-filled canals on their heads that are extremely sensitive. It is guessed that the sharks use their ampullae to find their prey (the muscles of the prey makes electric field when they contract). Sharks may also use them to get around in the water. A shark repellent have been made for scuba diver that sends out strong electric signals which then will irritate the sharks sensitive ampullae. ]]> 2019-11-11 15:25:30 UTC https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/409505158 ning_sang41 https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/409514420 Homing pigeons have these tiny magnetic particles in their beaks. They're mostly famous for being able to navigate over long distances. Their navigating skill is so reliable that they were used in WW1 and WW2 to deliver messages over enemy lines. It is also discover from researchers that these pigeons have specialized cells in birds' eye that may help them see the Earth's magnetic field . ]]> 2019-11-11 15:39:35 UTC https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/409514420 ning_sang41 https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/410000875 2019-11-12 15:09:43 UTC https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/410000875 ning_sang41 https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/410001478 2019-11-12 15:10:25 UTC https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/410001478 ning_sang41 https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/410002753 2019-11-12 15:11:53 UTC https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/410002753 ning_sang41 https://padlet.com/ning_sang41/nbqjjtkq87sm/wish/410011915 Bats have a magnetic substance in their body called magnetite and they use it as an "internal compass" to help them navigate.
