Stunning salamander could hold key to cell regeneration This creature is the stuff of myths but is actually real. Revered as a god by the Aztecs, the axolotl isn't your typical salamander.
[15] [16] The common mudpuppy never leaves its aquatic environment and therefore does not undergo morphogenesis; however, many salamanders do and develop differentiated teeth. [17] 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.
Tiger salamanders have been shown to travel up to 255 meters after their breeding cycles are complete, which is likely them returning to their original home ranges. [21] Some research has shown that females will travel farther than males. [22] However, a single tiger salamander has only a 50% chance of breeding more than once in its lifetime.
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.

A lens regeneration technique was trialled in a collaboration between Sun Yat-sen University and University of California, San Diego which was published in 2016. [8] The capsule of the lens was pierced with a smaller cut than in conventional cataract surgery – just 1–1.5 mm – and drained of its contents clouding the vision causing cataracts.
