skookum Posted July 11, 2012 #1 Share Posted July 11, 2012 Trout have cells in their noses that act like miniature compasses to help them navigate, a study has shown.The cells, which are believed to exist in other animals, contain iron-rich deposits of a magnetic material called magnetite. http://news.sky.com/story/958077/scientists-solve-trout-navigation-riddle Link to comment Share on other sites More sharing options...
lightly Posted July 11, 2012 #2 Share Posted July 11, 2012 A study was done that showed people have magnetic deposits in our brains ... right behind our noses. "follow your nose" Link to comment Share on other sites More sharing options...
Taun Posted July 11, 2012 #3 Share Posted July 11, 2012 It must be pretty easy for a trout... most streams aren't that wide and it's either upstream or downstream... 1 Link to comment Share on other sites More sharing options...
Junior Chubb Posted July 12, 2012 #4 Share Posted July 12, 2012 Its a shame that if we did ever have this kind of ability that the lack of need for it over time has seen it be eroded away. Orienteering would be a lot easier if we instinctively knew which way north was. It must be pretty easy for a trout... most streams aren't that wide and it's either upstream or downstream... You are spot on Taun (once they are in fresh water ), but the difficult part for Trout is finding the estuary of the river they are looking for, that is when the navigation factor really comes into play (finding the river from the sea).

csspwns Posted July 13, 2012 #9 Share Posted July 13, 2012 if tat were so then fish hooks would have magnets and make catching fish super easy but the magnet would rust sooo.. Link to comment Share on other sites More sharing options...
lightly Posted July 16, 2012 #10 Share Posted July 16, 2012 Some bacteria have built in compasses too... http://www.sciencedaily.com/releases/2008/12/081216201412.htm http://www.nature.com/scitable/knowledge/library/bacteria-that-synthesize-nano-sized-compasses-to-15669190 Link to comment Share on other sites More sharing options...
