Spiders

Believe it or not spiders actually breath air just like us. Spiders are air-breathing arthropods that have eight legs and with fangs that can inject venom into their victims. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms on our planet with some species having a life span of up to 25yrs.

Spider Identification

The Sydney Funnel-Web Spider is one of the world's most deadly spiders. Both the male and female carry atraxotoxin, one of the world's most dangerous toxins.

 

The Northern Tree Funnel-Web Spiders found in south-eastern Queensland and northern New South Wales are also highly venomous.

 

Danger time - the mature male funnel-web spider will wander around during hot humid nights, looking for a mate, and is known to enter homes, footwear, clothing, washing and swimming pools and is highly aggressive when disturbed or cornered and is able to inflict multiple bites

 

An anti-venom is available in most major hospitals and ambulance vehicles. First aid and medical attention (ambulance) should be sought as soon as possible, if bitten.

The Red-Back Spider can inflict a painful bite which can be fatal, especially to the young and elderly.

 

About 250 people receive the anti-venom each year.
