history - we have found out that scientist did not know about sea turtle navigation until 1779. When it was found they used a lot of medicine for the sea turtles.Also foxes have been identified as one of the first animal to use magnetic field to determine the direction they are going.

important individual s- Luigi Galavani- He was the founder of sea turtle navigation.He also did many experiments on different animals including a frog and he caused muscular contraction by touching its nerves with charged metal.

advantages and possible disadvantages - Sea turtle navigation helps the sea turtles find food so they will have something to eat. One advantage is that they have stronger muscles than humans so that means that they were born with the ability to swim.one disadvantage is that sea turtles are color blind.
