Varietal range differences
Axolotls are amphibians that are a type of salamander. The species is available in a variety of colors including nearly black, albino, golden and pied. Different strains differ in their ability to metamorphose into terrestrial salamanders, with many individuals unable to metamorphose.
Axolotls are suitable animals for primary schools, inner city schools and schools with space limitations as they live in small enclosures indoors and allow students to observe animal behaviour as well as teaching children the responsibilities involved in caring for an animal.
|Age at adult size:||16 cm. Axolotls are neotenic, that is, they attain sexual maturity without first metamorphosing from their gilled laval stage to the terrestrial adult stage.|
|Weight at birth:||Axolotls are oviparous or egg laying.|
|Gestation period:||Eggs are laid one day after indirect fertilization. At room temperature, embryos will hatch in two to three weeks.|
|Clutch size:||300–1000 eggs.|
|Sexual maturation:||From one year.|
Axolotls are not particularly interesting animals to observe. They are quite inactive, often not moving for a number of hours and when they do move, they are very slow. Axolotls are typically lazier in colder conditions and more active if their water is warmer.
Axolotls are interesting in that they can regenerate their body parts. If an axolotl is attacked by a predator, they can release one of their appendages in order to escape. The appendage will then grow back after a short period of time.
Axolotls are solitary animals and can be active at any time of the day but they are generally more active during the night. If exposed to bright light axolotls will usually seek shade or cover from the light, sheltering under overhangs, rocks or vegetation. They communicate with each other mostly via visual cues or chemical cues when mating. Both chemical and visual cues are also used to perceive their surroundings and discover prey.
In their natural environment, axolotls are a predator and will eat molluscs, fish, insects and worms. When different sized axolotls are kept together, cannibalism can be a problem if the animals are not fed appropriately.
