Crocodiles With Frickin' Magnets Attached to Their Heads

Brickwall writes "Florida, faced with a problem of crocodiles returning to residential neighborhoods after being relocated elsewhere, is trying to solve it by affixing magnets to the crocs' heads. The theory is the crocodiles use the Earth's magnetic field for navigation, and the magnets may interfere with that. What I'd like to know is, whose job is it to put the magnets on?" So far the magnet program appears to be working, unfortunately the crocs have started to collect huge amounts of take-out menus and child artwork.

The U.S. Fish and Wildlife Service designates it as Endangered, or in danger of extinction throughout all or a significant portion of its range.

    6. Re:Natural selection by CarbonShell · · Score: 5, Insightful

      First, this has nothing to do with natural selection.

      Actually you even show a clear ignorance for natural selection because you want to kill the ones that actually adapt and have become better hunters and can thus provide more food.
      I.e. the basis for evolution under the 'natural selection' (I'm kinda keeping it simple)

      Without wanting to start a pro/contra hunting argument, it is kinda like saying you are helping nature by going hunting.
      Uhm, no. What you are doing is simply cutting down the healthy ones and leaving the rest.
      While naturally speaking you should be hunting the sick, weak and old (like their natural predators do).
      But then which hunter wants to eat that meat?

      Second this is not only an issue with Crocs but with many more animals. Or should I say it is less of an animal then of a human issue.

      Unlike humans, animals still need to hunt for their food and are not particularly picky when they find something they can eat.
      And the easier they can get to it, the better.

      This is where we come in.
      * trash:
      It might seem like trash for us but anything edible you throw away will probably attract animals.
      Note, this does not exclude trash that is not thrown into the bin but can basically include anything we drop or store like bread crumbs or our basement food stock.

      * habitat:
      Rodents like mice, rats or cockroaches are typically problems in our habitats, among others to the above-mentioned trash issue.
      But you might think, hey these are only mice, we were talking about Crocs, you would have to remember that there are animals out there that hunt these, f.i. snakes.

      In addition to that our habitats are also warm/cool and protect us from the weather.
      And if they protect us, they also protect animals.

      Plus our other technological advances attract animals a well.
      F.i. Tar roads that can heat up quite nicely are ideal places for reptiles.
      Some animals love our hoses and wire isolation.

      * pets:
      Even our own pets are viable food sources to hunters and our domestication can cause them to lose their natural suspicion.
      And maybe that log they are sniffing is not really a log.

      * animal habitat reduction:
      As humanity increases in size we stupidly also increase our habitat size in crazy proportions and thus reduce that of the animals.
      This makes it easier for animals to enter our habitats.
      Kinda like if you compare the distance between towns 100 years ago to now. Back then the habitat spheres were far from each other. Today these spheres are much closer, touch or even overlap.

      Plus the amount of crocs might also be forcing the crocs to hunt in larger areas.

      But it would probably be more of the former then the latter.

      Humans are not interesting as a food source for most of the animal kingdom.
      To big, tough meat, hard to catch and dangerous.
      Nearly all accidents of animals attacking humans was because the humans were playing around in areas they should not be.

      More humans die in Africa due to Hippoes then to Crocs.
      More humans die in Australia to Jellyfish then to sharks.
