Unfortunately, this contradicts what most Californians believe; beliefs that are born out of media-driven hyperbole and erroneous, anxiety-filled public hearsay which is further compounded by medical misdiagnoses. Although people are free to disagree, this opinion has come about after more than two decades of constant research resulting in many publications in the scientific and medical literature. In addition to personal experience and thousands of spiders submitted to UC Rverside, the sources for this opinion encompasses conversations with, interactions with, and the cumulative knowledge of the following, who have experience or expertise in the state of California and, in some cases, are national or international experts:
Both sexes are glossy and darkly colored, ranging from blue-black, to black, to brown or dark-plum colored. The carapace covering the cephalothorax is almost hairless and appears smooth and glossy. Another characteristic are finger-like spinnerets at the end of their abdomen.
Spider behaviour They typically build silk-lined tubular burrow retreats with collapsed "tunnels" or open "funnel" entrances from which irregular trip-lines radiate over the ground. In some exceptions, which lack trip-lines but may have trapdoors, the silk entrance tube may be split into two openings, in a Y or T form.
Sydney funnel-webs burrow in sheltered habitats where they can find a moist and humid climate, for instance under rocks, logs or borer holes in rough-barked trees.
When potential prey, which includes insects, lizards or frogs, walks across the trip-lines, they rush out, subduing their prey by injecting their venom. The spiders can survive such immersion for up to twenty-four hours, trapping air bubbles on hairs around their abdomen.
During the day, they seek cover in cool, moist hideaways. After heavy rain, spider activity is increased as their burrows may be flooded. The lethal dose of venom from male Sydney funnel-web spiders for the crab-eating macaque Macaca fascicularis is 0.
Higher figures were found for other experimental animals, such as 1.
The average venom yield for a male is mg. However, it does not affect the nervous system of other mammals. There has been no reported case of severe envenoming by female funnel-web spiders, which is consistent with the finding that the venom of female specimens is less potent than the venom of their male counterparts.
Antivenom A funnel-web bite is regarded as a medical emergency requiring immediate hospital treatment. Patients are assessed every fifteen minutes, with further vials recommended if symptoms do not resolve.
The patient was a year-old boy who was bitten in February by a male funnel-web spider hiding in a shoe. One dose of antivenom requires around 70 milkings from a spider. The spider was described by the park as the largest specimen that it had seen.Blue Spider Case Study Gary was given the enticing opportunity to head the blue spider project because of his R&D background.
However, things did not turn out well for him and the entire project because he lacked the necessary skills and experience to head such a project.
