AXOLOTL EGGS DEVELOPMENT
Axolotls (Ambystoma mexicanum) are creatures belonging to the Ambystomatidae family, which falls under the Caudata order that includes salamanders and newts. They are known for their unique ability to maintain larval characteristics throughout their lives, a phenomenon called neoteny.
This also means they retain external gills and the ability to breathe through them, even when they are adults. The reproduction of axolotls primarily occurs through the deposition of eggs and external fertilization. Females release their eggs into the water, while males release sperm to fertilize them. After fertilization, the eggs develop into embryos within a gelatinous “shell.”
During the developmental process, the eggs gradually transform into larvae, which remain in the water. Over time, the larvae develop limbs and begin to breathe air, yet they still retain their external gills. This characteristic sets axolotls apart from other species of salamanders.
They are also subjects of scientific studies to better understand their extraordinary regenerative abilities, which allow them to regenerate damaged body parts. Despite their ability to reproduce in captivity, axolotls are threatened in their natural habitat, primarily due to the significant loss of habitat and pollution.
