What Happens When a Venomous Snake Bites Itself?

The video explores why snakes are generally immune to their own venom, despite its harmful effects on other animals. It discusses various mechanisms snakes use to protect themselves, such as molecular changes and natural inhibitors. Some snakes have evolved to produce antitoxins, while others modify their receptors to repel toxins. The video also highlights the potential of these natural inhibitors in developing better anti-venoms. However, not all snakes are immune, as demonstrated by cases where snakes have died from self-inflicted bites.

What is the primary reason most venomous snakes are not harmed by their own venom?

• Their skin is too thick for the venom to penetrate.

• They have evolved specific mechanisms to neutralize their venom.

• Their venom is not potent enough to harm them.

• They have a natural immunity to all toxins.

Which type of venom affects the nervous system by disrupting signal transmission?

• Neurotoxic venom

• Digestive venom

• Cytotoxic venom

• Hematoxic venom

How do some snakes modify their nerve receptors to protect against neurotoxins?

• By removing them entirely

• By covering them with a protective layer

• By changing their charge

• By making them larger

What is one way snakes can develop immunity to their own venom?

• By avoiding contact with their venom

• By changing their diet

• By constantly leaking small amounts of venom into their bodies

• By producing more venom

Why are natural inhibitors in snakes promising for developing better anti-venoms?

• They are cheaper to produce

• They are more effective against a wider range of venoms

• They do not require cold storage

• They are easier to administer

What happened when scientists made blacktailed rattlesnakes bite each other in 1932?

• Only one snake was affected

• They both died from the venom

• They became immune to each other's venom

• They both survived without harm

What does the case of the brown tree snake in 2016 suggest about venom immunity?

• Venom immunity is not necessary for survival

• Venom immunity is consistent across all snake species

• Some snakes can be harmed by their own venom

• All snakes are immune to their own venom
