The appearance of a dead axolotl (Mexican salamander) will vary depending on the cause of death, but a few general signs can be observed:
Lack of Movement: The most obvious sign is that the axolotl will not move or respond to its environment.
Floating or Sinking: A deceased axolotl might float at the surface of the water due to gas buildup or sink to the bottom because its muscles are no longer functioning to maintain buoyancy.
Changes in Color: Over time, the color of the axolotl may fade or become discolored as the animal decomposes.
Eyes: The eyes might appear cloudy or sunken, indicating the loss of vitality.
Gills: The gills may lose their vibrant color and may appear more relaxed or flaccid.
Body Rigidity: As rigor mortis sets in, the body becomes stiff and rigid.
Decay: After death, decay processes begin, which can quickly lead to an unpleasant odor and visible physical changes such as bloating and tissue breakdown.
If you notice your axolotl has passed away, it is best to remove it from the tank to prevent the spread of disease and preserve the health and well-being of any other animals in the tank. Proper disposal should then be considered to prevent any potential environmental harm.
Please remember that this description can be sensitive or distressing to some people. If you have found a deceased axolotl in your care, it may be necessary to consult with a veterinarian or an expert in amphibian care for guidance on handling the situation.
