Killer whales travel great distances in the oceans and they can find their way perfectly. Their navigation system cannot be solely based on visual. It is actually a sensorial organ using the magnetism principle that will intervene. Much quicker and more efficient than the best road map… well sea map

The Earth is a bit like a spherical magnet pierced like a torus (hence toroid magnet). The magnetic flux passes through the centre, leaving by a pole to reach the other one on the exterior border. Migratory birds are very sensitive to this magnetism as well as fish, butterfly and bat …

 

 

 

When the animal moves, it is going to follow or go across different magnetic lines. The different flux variations are going to be analysed by the brain as to calculate the position and the moves…

There are microscopically crystals of iron oxide, magnetic, called magnetite that will act as millions of micro compass and will orientate themselves according to these fluxes. This system is ultra sophisticated and still holds many mysteries. Therefore, in the middle of the ocean, an orca knows exactly its position when you have already sent your last flare… shame on you!

Dolphins have been found stranded on some coasts. For a long time it was thought that these phenomenon were collective suicides. We now know that it is not the case, there are 3 hypotheses

 

  • Pollution could deteriorate the navigation systems of the killer whales. The mercury and chloride contained in their body is alarming
  • During tempest, the magnetic fields, seriously disturbed, make calculation impossible …
  • The underwater buildings (cables, tunnels, oil structures) create or modify the magnetic field, misleading them. These artificial elements could act as jamming devices.
