Crocodiles With Frickin' Magnets Attached to Their Heads 304

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.

    Not trying to troll here, but why not just shoot them? Some crocs appear to love to be around humans, some not. Kill the ones who do, and let the ones who prefer to stay away from people have the chance to breed. In a few decades, we'll have a race of human-adverse crocs.

      Because most people don't like handbags with bullet holes in them. Same goes for wallets.

      As for belts, it's hard to get the holes consistently in the right places.

      In a few decades huh? Your understanding of genetics is as simplistic as your understanding of crocodile behaviour.

      As a previous poster has said, the objective is to relocate, not shoot them. This species of animal is also considered vulnerable [jrank.org] (quote) or facing a high risk of extinction in the wild. 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. The primary threat to this animal comes from habitat loss.

      Bad idea. Humans tend to find human-adverse aversive.

    • I guess as long as humans (and their pets, and their garbage) are tasty, human-adverse crocs are a pipe dream.
    • Is it proven that some specimens stay away from humans while others are unafraid of ut? What's the average lifespan of a croc? And is "stay-away-from-people" a dominant or recessive gene? Is it even a single gene?

      "A few decades" is probably a bit optimistic..

      But then again, if we don't kill those that get close to humans, we will effectively give the non-shy specimens an advantage. Hmh.

      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.

      • 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.

        The GP was specifically talking about artificial selection for a specific desired result - basically, de-facto breeding of shy crocs. This is interesting, though likely illegal and unworkable.

        You, on the other hand, having staked out the intellectual high ground by leveling accusations of ignorance, proceed with an only vaguely coherent rant about emulating the natural circumstances under which crocs get killed, add some sweeping statements and bold (even foolhardy) assertions about the mechanics of "natur [wikipedia.org]

      Actually, the article is about crocodiles and it is correct. There are crocodiles. About 2000, the species has made a great comeback from near extinction due in large part to the cooling canals at Turkey Point power plant. There are 186 Miles of cooling canals that are 5 feet deep and 200 feet wide. If you look on google maps near the homestead raceway, it looks like a giant radiator. This area is protected from all civilian interference and the animals thrive there. Other areas that the crocodiles go to are the biscayne bay and the everglades. they travel back and forth using the canal systems.

  • That will take care of the crocs.

    I guess there is some association here with "sharks with lasers". Though here in oz I know which one I rather swim near if I had to. From most to least dangerous (relative) I'd say: Crocodiles, box jelly and then sharks. Sharks eat people more by accident, box jellies just bump into you by accident ... crocs will hunt you if they see you and pursue by water or land.
