The plateau tiger salamander or Mexican tiger salamander (Ambystoma velasci) is a species of mole salamander in the family Ambystomatidae. An Axolotl that has gone through metamorphosis resembles an adult plateau tiger salamander, though the axolotl differs in its longer toes.
The axolotl (/ ˈ æ k s ə l ɒ t əl / ⓘ; from Classical Nahuatl: āxōlōtl [aːˈʃoːloːtɬ] ⓘ) (Ambystoma mexicanum) [3] is a paedomorphic salamander closely related to the tiger salamander. [3] [4] [5] It is unusual among amphibians in that it reaches adulthood without undergoing metamorphosis. Instead of taking to the land, adults ...
The mole salamanders (genus Ambystoma) are a group of advanced salamanders endemic to North America. The group has become famous due to the study of the axolotl (A. mexicanum) in research on paedomorphosis, and the tiger salamander (A. tigrinum, A. mavortium) which is often sold as a pet, and is the official amphibian of four US states.
The Blotched tiger salamander (Ambystoma tigrinum melanostictum) is a species of Mole salamander. Tiger salamanders are large, with a typical length of 6–8 in (150–200 mm). They can reach up to 14 in (36 cm) in length, particularly neotenic individuals. Adults are usually blotchy with grey, green, or black, and have large, lidded eyes.
Spotted salamander: Ambystoma maculatum (Shaw, 1802) Abundant Statewide Marbled salamander: Ambystoma opacum (Gravenhorst, 1807) Species of special concern Primarily southeastern counties, extends into central counties, scattered records in eastern counties Tiger salamander: Ambystoma tigrinum (Green, 1825) Extirpated [5]
The axolotl is also a relative of the tiger salamander. [33] [34] Axolotls live in a paedomorphic state, retaining most characteristics of their larval stage for their entire lifespans. While they never metamorphose under natural conditions, metamorphosis can be induced in them, resulting in a form very similar to the plateau tiger salamander.
The long-toed salamander (Ambystoma macrodactylum, Baird 1849) [4] is a mole salamander in the family Ambystomatidae. This species, typically 4.1–8.9 cm (1 3/5–3½ in) long when mature, is characterized by its mottled black, brown and yellow pigmentation, and its long outer fourth toe on the hind limbs.
The barred tiger salamander typically grows from 7.6 to 16.5 cm (3.0 to 6.5 in), but neotenic forms can grow to lengths of 17.8 to 38.1 cm (7.0 to 15.0 in), [3] and is one of the largest species of salamander in North America. It has a broad head and a sturdy body.
