Axolotl: The Forever-Young Salamander

Meet the axolotl—Mexico’s water-dwelling salamander that stays in its juvenile form throughout life.

Neoteny Explained

Unlike most amphibians, axolotls retain gills and remain aquatic adults—a rare trait called neoteny.

Regenerative Abilities

They can regrow limbs, spinal tissue, heart, eyes—even parts of their brain—without leaving scars.

Habitat & Range

Native to Lake Xochimilco and Lake Chalco canals near Mexico City, now severely endangered.

Appearance & Size

Axolotls reach ten inches long, come in gray with spots or albino variants bred as pets.

Diet & Behavior

At night these carnivores suck up worms, crustaceans, small fish—and even sometimes bite siblings.

Cultural Symbol & Conservation

Named after Aztec god Xolotl; now critically endangered. Conservation projects focus on habitat restoration and breeding.

Scientific Importance

Scientists study axolotls extensively, hoping regenerative clues may one day unlock human healing potential.
