These salamanders snack on each other (but don't die) | Luis Zambrano

The video explores the unique biology of axolotls, amphibians that retain juvenile traits and excel in regeneration. Native to Mexico City, axolotls evolved in stable habitats, leading to neoteny. They can regenerate limbs and resist cancer, with a genome much larger than humans. Conservation efforts are crucial as their wild population is threatened by pollution and habitat loss. Scientists hope to apply axolotls' regenerative abilities to human medicine.

What makes axolotls different from many other amphibians?

• They can fly.

• They live in trees.

• They are completely terrestrial.

• They retain juvenile features and do not undergo metamorphosis.

Why did axolotls evolve to retain their juvenile features?

• Due to a lack of predators and a stable aquatic environment.

• Because they are afraid of land.

• To avoid predators on land.

• To conserve energy.

What is a key feature of axolotls' regenerative abilities?

• They can regenerate only their tails.

• They cannot regenerate any body parts.

• They can regenerate limbs, spines, and even parts of their brains.

• They can regenerate only their skin.

What is unique about the axolotl's genome?

• It is identical to the human genome.

• It is smaller than that of humans.

• It is more than 10 times longer than the human genome.

• It has no repeated sequences.

What has caused the decline in the axolotl population?

• Lack of food.

• Natural predators.

• Pollution and habitat destruction.

• Overfishing by locals.

What efforts are being made to help axolotls in the wild?

• Building new lakes.

• Regenerating their ecosystem and supporting traditional farming.

• Introducing new predators.

• Moving them to zoos.

What potential human application is being researched from axolotls?

• Increased lifespan.

• Flying abilities.

• Enhanced swimming skills.

• Regenerative abilities and tumor suppression.
