A brief introduction to funnel web spiders

1. Life habits

Funnel web spiders are about 5 centimeters long and spend most of their lives in underground nests. Only males climb out of the ground in search of a mate.

This kind of spider will spit spider silk in the nest, and when there is prey at the entrance to the nest, the spider silk will vibrate. Then the spider jumps out to attack its prey.

2. The shape of weaving net

Not all cobwebs are radial, they have other shapes. The most typical is the funnel-shaped spider web. Like most other species of spiders, funnel spiders like to come out at night.

After weaving a web, funnel spiders hide in the "hole" of the funnel and wait for their prey to take the bait. Although the web is not sticky, the spider silk is crisscrossed, and the legs of passing insects are easily wrapped around the silk. The funnel spider senses the slight vibration of the web and knows that its prey has taken the bait and will immediately attack and bite its prey.

3. Venom composition

The main component of the venom is (adrenotoxin), which is toxic to primates and dogs, but not toxic to rabbits. Atraxotoxin (adrenotoxin) can cause changes in the membrane potential of nerve cells, causing the autonomic nervous system to secrete large amounts of acetylcholine, epinephrine and noradrenaline. The toxicity of male is about 4 times that of female.

Second, how to treat the funnel web spider bite?

1. Pressure bandage method

The bite can be pressed to compress the venom in the subcutaneous tissue, sometimes it can be naturally denatured and lose its toxicity. When being sent to the hospital for treatment or even injected with serum, experts recommend that pressure bandages should still be kept in the affected area, as in many cases, systemic symptoms can occur as soon as they are released.

2. Antivenom serum

After injection and then injected with antivenom, the symptoms can be alleviated quickly. This antivenom is made from Australian ComnonwealthSerumLaboratoty and rabbit serum. The price of each dose in the year 2000 is US $760. According to the study, it is pointed out that the serum made from Sydney funnel web spider Atraxrobustus can be used for different kinds of Atrax, but it needs a large dose, and this serum can also be used for all kinds of bites of blue mountain funnel web spider Hadronyche. No deaths have been reported since the serum was launched in 1980 (13 deaths from 1927 to 1980).
