Animals Inspiring the Armor of the Future

The video explores how natural armor in various organisms inspires human protective gear. Gar fish scales lead to puncture-proof gloves, chitons' vision-capable armor inspires multifunctional armor, and conch shells inform impact-resistant helmets. Spider silk is considered for bulletproof vests, and polydopamine from mussels offers a non-toxic flame retardant solution.

What inspired the development of puncture-proof gloves?

• The silk of spiders

• The shells of conchs

• The eyes of chitons

• The scales of gars

How do chitons protect themselves from threats?

• By producing a sticky substance

• By having eye-like structures all over their bodies

• By hiding in the sand

• By using their strong shells

What is a unique feature of chiton armor?

• It changes color

• It is magnetic

• It can see threats

• It is transparent

What makes conch shells particularly strong?

• Their crisscross pattern of calcium carbonate and proteins

• Their large size

• Their spiral shape

• Their smooth surface

What is the main component of conch shells?

• Magnesium

• Iron

• Calcium carbonate

• Silica

Why is spider silk considered a potential replacement for Kevlar?

• It is more colorful

• It is lighter and more flexible

• It is cheaper to produce

• It is easier to manufacture

What is the main challenge in using spider silk for protective gear?

• It is not flexible enough

• It is not strong enough

• It is difficult to mass-produce

• It is too expensive

Why are silkworms preferred over spiders for silk production?

• Their silk is stronger

• They are less aggressive

• They are easier to farm

• They produce more silk

What is polydopamine primarily used for in nature?

• To help mussels adhere to surfaces

• To attract mates

• To protect against predators

• To provide buoyancy

How does polydopamine act as a flame retardant?

• By reflecting heat

• By creating a barrier

• By binding to free radicals

• By releasing water
