📖 1. Overview
It is a representative amphibian exhibiting neoteny, breeding underwater while retaining its flower-like larval external gills into adulthood without undergoing metamorphosis.
🌐 Wikipedia Summary ExtractThe axolotl is a species of mole salamander. It is neotenic, reaching sexual maturity without undergoing metamorphosis, and the adults remain fully aquatic with obvious external gills. Axolotls may be difficult to distinguish from the larval stage of other neotenic adult mole salamanders, in particular the tiger salamander, or other species such as mudpuppies.
🦴 2. Anatomy & Morphology
It possesses an astonishing stem-cell regeneration capacity, able to regrow not only limbs and tail but also the spinal cord, parts of the heart, and even damaged brain tissue completely to their original state without scarring.
🔍 3. Ecology & Behavior
With a massive genome of 32 billion base pairs (32 Gb)—10 times the size of the human genome—it serves as a key model organism in modern regenerative medicine and aging research.
🇰🇷 4. Connection to Korea
It is one of the most popular amphibians, widely known in Korea under the name 'Wooper Looper.'
