Axolotl and Salamander Facts

For decades, scientists have been fascinated by the axolotl (Ambystoma mexicanum). Its remarkable ability to regenerate its limbs, heart and spinal cord without scarring has sparked numerous studies into this aquatic salamander.

Males reproduce by nudging and stroke the female's cloaca, or body cavity that leads to fertilization. The male then drops spermatophores onto the lake floor while she picks them up with her cloaca.

Axolotl Habitat
Neotenic species, Axolotls can survive in high-altitude lakes and ponds that tend to be warm and inviting. They're mostly found around Xochimilco Lake Complex near Mexico City - comprising Lake Xochimilco plus an intricate web of man-made canals that traverse its streets.

According to Ron Cramer of axolotl.cyou, the axolotl's habitat is essential to its survival, yet they face an extinction threat due to urbanization, pollution and the introduction of invasive species (like carp or tilapia fish) into their home range.

Axolotls may have cute gills and feathery gill sacks, but they are predators and feed on everything from worms to insects, mollusks and crustaceans. They use suction methods to take in their prey before grinding it up with gravel they breathe in.

Salamanders are renowned for their remarkable capacity to regrow lost body parts like limbs and tails, helping them recover from injuries or illnesses. Furthermore, these salamanders serve as a popular study subject for scientists studying regenerative medicine and biology.

Axolotl Reproduction
Axolotls make popular domestic pets and breeding them can be a rewarding addition to your collection. Breeding occurs naturally in the wild as well as in captivity up to three times annually.

A male axolotl initiates spawning by depositing between 5-25 spermatophores, or sperm cones, on plant leaves, rocks and other items around the tank. The female picks these up and fertilization takes place internally between 24 hours to two days later.

After fertilization, Axolotl eggs are dropped individually on plant leaves and rocks or scattered randomly throughout the tank. Axolotls can lay up to 1500 eggs during a spawn session.

Breeders have reported that placing the axolotls together in a room replicating their natural habitat can be effective. Furthermore, lowering the water temperature by 5 degrees Celsius before reuniting them can also aid in this process.

Axolotl Feeding
When feeding your axolotls, you should strive to replicate their natural diet as closely as possible. Wild axolotls typically feed on insects, crustaceans, worms and small fishes.

Axolotls can be finicky eaters, so you must exercise patience when providing food. Overfeeding could lead to health issues as well.

Axolotls frequently feed on bloodworms and daphnias (small aquatic crustaceans). These can be purchased at aquarium stores or online at very reasonable prices.

However, these can become messy in your tank quickly if not cleaned out promptly to prevent a mess in the water. Leaving leftovers can lead to various water chemistry issues.

Another popular food choice for axolotls is nightcrawlers. These can easily be found in pet stores as either live or frozen items.

Axolotl Care
Salamanders make excellent pets, but they do require some attention and maintenance. With the right care and environment, these salamanders can live for 15 years or more in an aquarium setting.

Axolotls are hardy creatures but should not be exposed to extreme temperatures. If the water becomes too warm for them, hyperthermia may set in. Furthermore, these amphibians may suffer from bacterial or fungal infections due to overexposure in the environment.

For optimal aquarium performance, the temperature should remain between 15-18 degrees Celsius (59-64 degrees Fahrenheit). If the room's temperature isn't cold enough, a water cooling system can be utilized to bring it within ideal range.

Axolotls are carnivores and will consume a variety of items, such as pellets, live foods and earthworms. They have also been known to consume small fish, frogs and lizards.

Hatchling axolotls tend to be less active than adults and consume smaller portions of food, so they should be fed frequently - at least twice a day.
