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 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.
These salamanders are mostly terrestrial and eat invertebrates, although some species are known to eat smaller salamanders. They can be found throughout the US and some areas of Canada in damp forests or plains. This family contains some of the largest terrestrial salamanders in the world, the tiger salamander and the coastal giant salamander ...
Eurycea neotenes, also known as the Texas salamander, Bexar County salamander, Edwards Plateau salamander, or Texas neotenic salamander, [3] is a species of entirely aquatic, lungless salamander native to the United States. It is endemic to central Texas, near Helotes, in Bexar County.
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.
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.
Aquatic salamander teeth are used to hinder escape of the prey from the salamander; they do not have a crushing function. [17] This aids the salamander when feeding. When the salamander performs the "suck and gape" feeding style, the prey is pulled into the mouth, and the teeth function to hold the prey inside the mouth and prevent the prey ...
