'There were hundreds of tarantulas crossing the road, all moving in the same direction,' he says. 'For 100 yards or so, there was easily a tarantula every meter or two. It was pretty incredible.'" http://www.nwf.org/nationalwildlife/...988&issueId=70 Cheers, Carl Fogel Dear Carl, While I don't dispute what Sissom saw, the article doesn't reveal whether that occurance was normal, a rarity or even a one off.

Now you know I didn't make it up. I thought it was strange behavior for spiders who normally fight for territory. In the march over my legs they were only about 6" apart from each other. I guess they were focused on their mission of marching. Nature is fun to participate with, and not just watch Animal Planet. Bill Baka |

I tried the pencil test since I had one in the car and the test turtle bit it clean in half. Feisty little buggers. Bill Baka Dear Bill, Usually, the claim is a broomstick. In practical tests, even large common snappers were barely able to break a pencil. This is unsurprising, since they don't eat sticks or gnaw bones. The tell-tale sign of the myth is that the stick/pencil/broom-handle is always bitten in _half_, which is impossible. A turtle's beak would have to divide any stick into _three_ pieces, leaving the middle section hopelessly wedged in the lower beak. No one ever mentions having to remove the chunk of wood stuck in the turtle's mouth. A large common snapper's head is about the size of a big fist--and all the jaw muscles are right there on the side of the skull, not lurking up the elbow. Common snappers are chiefly bottom-dwelling carrion feeders, but will grab live crayfish, frogs, ducklings, small snakes, and unwary fish. If you keep common snappers as pets, you learn that they seize freshly killed bullfrogs with their beaks and then tear them to pieces with their powerful clawed forelegs. My largest pet was a plump 28-pound female. She couldn't bite through a bullfrog leg, but she could rip the amphibians in half with her claws and gulp them down. A foolish claim is floating around the internet about snapping turtles having thousand-pound bites. Possibly someone was thinking of a 150-lb alligator snapper, an entirely different beast than a common snapper, which is huge in the wild at 40 pounds. (The record weight for a wild common snapper was a 68-lb Nebraskan, much to the embarrassment of certain Southern states. The commonly cited 86-lb common snapper was a huge, overfed captive, which was kept in a swill barrel and bore about as much resemblance to a normal snapper as Chalo does to a typical RBT poster.) Here's a fair example of a wild snapper record: http://www.kdwp.state.ks.us/news/lay...pping_tu rtle And another state wild record: http://www.bio.davidson.edu/people/m.../bigturtle.htm (It's not uncommon to catch two snappers in the same trap like the North Carolina giant and his little friend. You bait a simple box trap with liver scraps, and the snappers follow the scent through the water. I once had a hell of a time getting a pair of 18-pound males out of a large box-trap that I'd foolishly built when I expected only a single 10-lb snapper if I was lucky.) Here's a pdf with some details about record weights: http://wfs.sdstate.edu/wfsdept/Publi...0M.S.-1968.pdf "What perhaps makes chelydrids most interesting is what they eat, or at least what they bite. ‘Large individuals are known to have caused injury to people unwary enough to step into or swim in the water near them, and they are quite capable of removing a toe or finger if given the opportunity’ (Alderton 1988, p. 112). Indeed, they are anecdotally credited with being able to ‘bite through a broom handle’. For his excellent TV series ‘O’Shea’s Dangerous Reptiles’, Mark O’Shea decided to test this dubious assertion. With the help of a colleague he caught the largest and nastiest alligator snappers he could, ****ed them off by poking them, and then ****ed them off some more by shoving a broom handle into their mouths. All the turtles bit happily, and bit hard. And as impressive as it was, sad to say not one turtle was powerful enough to cleave neatly through 25 thick mm of solid wood, which to be honest isn’t much of a surprise." "Rather more rigorous tests were applied by Herrel et al. (2002) who tested the bite force of numerous diverse turtles, including both snappers and alligator snappers. They found snappers to have bite forces of between 208 and 226 Newtons, and alligator snappers of between 158 and 176 N." http://darrennaish.blogspot.com/2006...ite-lunge.html Here's the scholarly Herrel et al. article mentioned above, with enough graphs to please Robert Chung and an early table of bite forces for a variety of turtles, with a common snapper (chelydra serpentina) 6th on the awkwardly rotated alphabetical list: http://www.blackwell-synergy.com/doi...1.2002.00459.x The roughly 10-lb common snapper managed a bite force of 209 Newtons, or about 47 pounds, only 5% of the wild thousand-pound claims. Most RBT posters can break a hundred pounds. You do not, however, want to let even a baby snapper with a 2-inch shell get its jaws on your finger, whose flesh is considerably easier to damage than a pencil and much more sensitive. (Guess how I know.) Cheers, Carl Fogel |

Saying the turtle bit the pencil 'clean' in half was a bit of overstatement, but I still had a broken pencil, so I wasn't about to get my fingers near his mouth. The ones I tried to move off the freeway were in the 5 to 10 pound range, so no spectacular whoppers in that bunch. Still the number of flat turtles on the road was a grim testament to the fact that cars trump shells. If you got bit as you say that kind of means you tried keeping one as a pet, and I had a baby alligator who would bite my finger but not draw blood. The alligator would not let go and I could pick him up while he was clamped to my finger. I would not want to try that with a snapping turtle. Good day. Bill Baka |

Cheers, Carl Fogel I can relate to your problems. My first digital camera had a horrendous boot time and shutter delay which cost me many fine shots. Now I carry my 35mm Minolta and a bag of lenses but still have to get it focused and set the exposure for the shot.. Maybe I'll just take all my lunch money for the year and buy an overpriced super digital, which will be old news by next year. It ain't easy riding AND taking pictures. Bill Baka |
