Name || Axolotl, Mexican Salamander, Mexican Axolotl, Mexican Walking Fish |
Scientific Name || Ambystoma mexicanum |
Conservation Status || Common in captivity but threatened in the wild. |
Habitat || As their name suggests, the axolotl originates from Mexico. They are originally from Lakes Xochimilco and Chalco, but lake Chalco no longer exists and Xochimilco survives only as a network of canals and lagoons. These bodies of water are muddy bottomed and rich in plant and animal life. They are now found all over the world as pets. |
Unique Features ||
The axolotl remains in its larval form, meaning that it retains its gills and fins, and doesn't develop the characteristics of other adult salamanders. It grows much larger than a normal larval salamander. It is completely aquatic, and although it does possess rudimentary lungs, it breathes primarily through its gills and to a lesser extent, its skin.
Social Behaviour ||
Very little is known about axolotl behaviour in the wild, they can be aggressive toward one another and will bite off each others gills, feet and tails.
Diet ||
The Axolotl is carnivorous and feeds on worms, tadpoles, insect larva, crustaceans and wounded fish.
Reproduction ||
Sexual maturity is reached between six months and a year. The female lays 200-600 eggs, which she attaches to plants with her back legs. These eggs hatch in two to three weeks but remain attached to plants. At two weeks of age they begin swimming in search of food
Life Cycle ||
In captivity axolotls usually live for 12-15 years, although they have been recorded living up to 25 years. Their lifespan in the wild is unknown.
Relatives ||
The axolotl is closely related to other salamanders, particularly the tiger salamander.
Interesting Facts :
- The axolotl is though to be a delicay when roasted.
- The axolotl is fully capable of complete limb re-growth.
Breeding Programme ||
Wellington Zoo is not currently involved in a axolotl breeding programme.
Environmental Conditions ||
The axolotl is threatened in the wild due to pollution, exploitation and introduction of predators (sports fish). Wild axolotls are becoming so scarce that permits are required for the possession and taking of a wild specimen. Their original lake habitat was drained and filled to make room for the growth of Mexico City.
At Wellington Zoo ||
We have one adult axolotl and 39 offspring in the Scaly Nursery.
