Why Invasive Tadpoles Turned Cannibal | SciShow News

The video discusses the invasive cane toads in Australia, highlighting their impact on local wildlife and their unique cannibalistic behavior. Researchers found that cane toad tadpoles in Australia consume their own species' eggs and larvae, a behavior not observed in their native South America. This may be due to competition and the presence of toxins in the eggs. The video then shifts to ALS, a disease affecting voluntary muscle movement. It explores a new method using brain-computer interfaces that allow ALS patients to communicate through auditory feedback, offering hope for improved communication despite the disease's progression.

What was the original purpose of introducing cane toads to Australia?

• To provide food for native animals

• To study their behavior in a new environment

• To increase biodiversity

• To control insect pests

What unique behavior do cane toad tadpoles in Australia exhibit?

• They do not eat any eggs in their native range

• They only eat native frog eggs

• They consume their own species' eggs and larvae

• They avoid eating any eggs

What triggers the feeding frenzy in cane toad tadpoles?

• Toxic chemicals in the jelly around the eggs

• The availability of food

• The absence of native frogs

• The presence of predators

What is ALS and how does it affect the body?

• A disease that strengthens muscles

• A disorder that enhances brain function

• A nervous system disease that deteriorates voluntary muscle movements

• A condition that improves communication skills

How do brain-computer interfaces help ALS patients communicate?

• By reading their thoughts directly

• By using auditory feedback to interpret brain signals

• By improving muscle strength

• By enhancing their vision
