AXOLOTL
Ambystoma mexicanum
DESCRIPTION
The axolotl, also known as the Mexican walking fish, is a neotenic salamander that retains its larval features throughout its life. It has a distinctive appearance with external gills that resemble feathery structures on either side of its head, a wide head, and a flattened body. Axolotls are known for their regenerative abilities, capable of regrowing limbs, spinal cord, heart, and even parts of their brain, making them a subject of scientific research.
FUN FACTS
- Axolotls are often referred to as 'Mexican walking fish,' but they are actually amphibians and not fish at all
- They are unique among amphibians for their ability to remain in a larval state throughout their lives, a phenomenon known as neoteny
- | The axolotl's regenerative capabilities are so advanced that they can regrow entire limbs and even parts of their heart and brain
- This has made them a focal point for scientific research into regeneration and potential medical applications for humans

CR
Critically Endangered
IUCN Red List Status
- Population Status
- The axolotl population is critically endangered due to habitat loss and pollution.
- Wild Population Estimate
- Less than 50 in the wild.
- Population Trend
- Decreasing
- Endangered
- 1
- Threats
- Main threats include habitat destruction due to urbanization, pollution, and the introduction of invasive species that compete for resources.
- Conservation Program
- Conservation efforts include habitat restoration and breeding programs in captivity to help increase population numbers.
- Predators
- Birds, fish, and other aquatic predators such as turtles.
- Defense Mechanisms
- Axolotls can regenerate lost body parts, which serves as a defense mechanism against predation.
- Compatible Animals
- small fish, snails, certain amphibians
- Found in Zoos
