I Vacuum Venom from the World's Deadliest Spider

The video explores the funnel web spider, its habitat, and the dangers of its venom, which is particularly lethal to humans. It explains the process of collecting venom and producing antivenom at the Australian Reptile Park. The venom's effects on the human nervous system are detailed, highlighting the importance of antivenom in preventing fatalities. The video also covers the collection and milking of spiders for venom extraction, emphasizing the role of public donations in maintaining the spider stock. Despite the venom's lethality, no deaths have occurred since 1981 due to effective antivenom programs.

What is the primary reason funnel web spiders are dangerous to humans?

• They are aggressive and attack frequently.

• They are large and intimidating.

• They can fly and cover large distances.

• Their venom is fast-acting and deadly.

How does funnel web spider venom affect the human nervous system?

• It slows down neurotransmitter release.

• It causes neurons to close ion channels.

• It prevents ion channels from closing, causing chaos.

• It strengthens the nervous system.

Why are humans more affected by funnel web venom compared to other mammals?

• Humans are more likely to provoke spiders.

• Humans have weaker immune systems.

• Humans are more exposed to spiders.

• Humans have a specific site in sodium ion channels that the venom targets.

What is the main reason for the accidental lethality of funnel web venom to humans?

• The venom is a recent evolutionary development.

• The venom is designed to target large mammals.

• The venom evolved for effectiveness against insects but affects primates.

• The venom evolved to target primates specifically.

What is the role of rabbits in the production of funnel web spider anti-venom?

• Rabbits are immune to the venom and provide a natural cure.

• Rabbits are injected with venom to develop antibodies.

• Rabbits are used to test the venom's lethality.

• Rabbits are used to attract spiders for venom collection.
