Ambystoma RivulareĬalled the brook salamander, this species is characterized by the variation in coloration and body shape between males and females, in terms of body length and width, body shape, and distance from the extremities. Which are distributed on its body in a uniform manner, which is responsible for the dark hue that characterizes them. This salamander is one of those that manage to retain many characteristics of its larval stage, such as its coloration, also showing rows of yellow spots on its belly, and fins with mottling, also present, although sparsely, melanophores. Ambystoma Ordinarium Michoacan SalamanderĬalled Michoacan salamander, it can reach 19 cm when they have reached adulthood, the head shape is flattened and narrow.Īlthough its color can vary according to the environment, usually have a dark coloration, ranging from black to greenish very bright throughout his body, with small circular yellowish spots that are distributed in rows along his body and its tail. On its belly there is a lighter shade of color, becoming in some cases almost white. This axolotl is called thin-skinned, its body has a coloration that varies between brown and olive green, with irregular and yellowish spots, very sporadic on the body, and are accentuated towards the tail area. Its tail has a length that can match the rest of its body, laterally between its front and hind legs some undulations resemble rings that surround its trunk. Morphologically their front and hind legs lack membranes between their fingers, with a very flat head, and very smooth skin. This species is one of the rarest of axolotls, they have relatively small sizes that may not exceed 14 cm.

They have a very peculiar color of pale yellow on their belly, also their whole body is dotted with non-uniform moles of a yellowish coloration.Įxpert Tip: The color of this type of axolotl varies among populations and depending on the size of the animal, the sizes and shapes of its moles can be smaller or larger. Known as mountain axolotls, they are characterized by having a very dark coloration throughout their body, which depends largely on the colors present in the existing environment at the bottom of the streams where they live. There is a classification of axolotl colors, those of streams and those of lakes, dams, ponds, and aquariums, let’s see.

iridophores show a coloration that tends to be dark or black and is called hypermelanistic. Other axolotls lack the reflection-producing cells, i.e. In these axolotls, the cells that produce the pigmentation do it in a normal way.īut when they are developing from the embryo, these cells fail to reach completely the whole embryo, producing white color and dark eyes. On the other hand, there are those of white color, known as leucistic. Purines: these are organic compounds, which crystallize iridophores, organic compounds called purines that, when crystallized, produce an optical phenomenon where the light looks different from every angle you look at it and shows an almost crystalline appearance, iridescent, and bright, these are produced by chromatophores called iridophores.Īlso, among the variations of axolotl colors we find the varieties of albinos, with shades that tend to be whitish or yellowish, these animals have red eyes.Pteridines: these are the yellow and reddish-colored pigments that produce the chromatophores known as xanthophores.Eumelanin: is the pigment that produces the brown and blackish coloration of the chromatophore called melanophore.The main reason for the axolotl colors is the cells that possess pigments capable of reflecting light, these cells are known as chromatophores, disperse their granules, the classification of these cells depends on the coloration of the pigments, and they can be: Enigma Axolotl The reason for Axolotl’s many color variations
