yang membuat sama di sini adalah keberadaan insang sebagai alat pernapasan. pada salamander dewasa insangnya sudah hilang, sama seperti kodok dan katak yang kehilangan insang saat dewasa. jadi tetap tidak bisa disamakan dengan jangkrik atau belalang.

Jadi salamander dewasa juga bernafas melalui paru2 & permukaan kulit?

"Salamander is a common name of approximately 500 species of amphibians. They are typically characterized by a superficially lizard-like appearance, with their slender bodies, short noses, and long tails. All known fossils and extinct species fall under the order Caudata, while sometimes the extant species are grouped together as the Urodela" (Herpetological Monographs 7 (7): 77–93. 1993)

Respiration differs among the different species of salamanders. Species that lack lungs respire through gills. In most cases, these are external gills, visible as tufts on either side of the head, although the amphiumas have internal gills and gill slits. Some salamanders that are terrestrial have lungs that are used in respiration, although these are simple and sac-like, unlike the more complex organs found in mammals. Many species, such as the olm, have both lungs and gills as adults. (Lanza et al., 1998)

Some terrestrial species lack both lungs and gills and perform gas exchange through their skin, a process known as valerian respiration in which the capillary beds are spread throughout the epidermis, and inside the mouth. Even some species with lungs can respire through the skin in this manner.
The skin of salamanders secretes mucus, which helps keep the animal moist when on dry land, and maintains their salt balance while in water, as well as providing a lubricant during swimming. Salamanders also secrete poison from glands in their skin, and some additionally have skin glands for secreting courtship pheromones. Salamanders regularly shed the outer layer of their skin (the epidermis) as they grow, and then eat the resulting slough. (http://www.giant-salamander.com)
