The fate of whales

The news often comes to us: a group of whales have been trapped on a remote beach without backing down or advancing, and have been left to die. Why do intelligent beings invade this path?

The event also surprised Aristotle, who seems unright. Current biologists have created numerous theories to clarify this unfortunate event.

A biologist discovered worms in the ears of sunken dolphins and deduced that they had spoiled the dolphin navigation system.

Then it was observed that all dolphins had these parasites. Another theory said that whales, being terrestrial animals, were heading towards Iurre following ancient memories. This theory would encourage people to think that whales did not exist millions of years ago.

In recent years, more solid theories have been published. Dan Odell, biologist at the University of Miami, analyzes the Gulf of Mexico Currents, analyzing thermal images obtained by satellite. Sometimes small currents move to cold coastal waters to get away and disappear. Currents that circulate outside the channel can carry chiripirones that are the main food of the whales.

Whales following the Chipirones quickly consume these limited resources and the groups' traps are because they are too close to the coast and without food.

California scientists propose another theory: that whales conform to magnetic minimums. At magnetic minimums, the Earth's magnetic field has minimal values. When compared to the location of the whales with the terrestrial magnetism, it has been observed that 95% of the encryption has occurred in places where the lines of magnetic minimums and the coast are cut together. If the cause of whale behavior were this, it would be an event similar to that of the atomic pile that has lost its way.
