A terrestrial salamander catches its prey by flicking out its sticky tongue in an action that takes less than half a second. In some species, the tongue is attached anteriorly to the floor of the mouth, while in others, it is mounted on a pedicel.

It is rendered sticky by secretions of mucus from glands in its tip and on the roof of the mouth.

Imam Ali (PBUH) said: When our Qaim rises, the sky will send down its drops, the earth will grow its plants, enmity will come out from the servants hearts (in order that they live in peace and brotherly love), and savages and beasts will continue to live together peacefully.

When struggling prey is advanced into the salamander's mouth, the teeth tips relax and bend in the same direction, encouraging movement toward the throat, and resisting the prey's escape.

Many salamanders have patches of teeth attached to the vomer and the palatine bones in the roof of the mouth, and these help to retain prey. All types of teeth are resorbed and replaced at intervals throughout the animal's life.

The Holy Prophet (peace be upon him and his progeny) said: The person who dies and has not known the Imam of his time (Imam Mahdi (PBUH) is that of the present time) has died the same as one who died during the Age of Ignorance.

Most species of salamander have small teeth in both their upper and lower jaws. Unlike frogs, even the larvae of salamanders possess these teeth.

Although larval teeth are shaped like pointed cones, the teeth of adults are adapted to enable them to readily grasp prey.

The crown, which has two cusps (bicuspid), is attached to a pedicel by collagenous fibers. The joint formed between the bicuspid and the pedicel is partially flexible, as it can bend inward, but not…

The Holy Prophet (peace be upon him and his progeny) said: Allah will raise a man from my progeny, from my Ahlul Bayt, by whom the earth will be filled with justice thoroughly the same as it has been filled with injustice and oppression.

Cannibalism sometimes takes place, especially when resources are short or time is limited. Tiger salamander tadpoles in ephemeral pools sometimes resort to eating each other, and are seemingly able to target unrelated individuals.

Adult blackbelly salamanders (Desmognathus quadramaculatus) prey on adults and young of other species of salamanders, while their larvae sometimes cannibalise smaller larvae.

The Holy Prophet (peace be upon him and his progeny) said: Al-Mahdi is of my progeny from the sons of Fatimah (peace be upon them).

Salamanders are opportunistic predators. They are generally not restricted to specific foods, but feed on almost any organism of a reasonable size.

Large species such as the Japanese giant salamander (Andrias japonicus) eat crabs, fish, small mammals, amphibians, and aquatic insects.

Smaller dusky salamanders (Desmognathus) in the Appalachian Mountains, their diet includes earthworms, flies, beetles, beetle larvae, leafhoppers, springtails, moths, spiders,…

The Holy Prophet (peace be upon him and his progeny) said: No drop is more beloved with Allah, Almighty and Glorious, than the drop of blood which is poured in the way of Allah.

The external gills seen in salamanders differs greatly from that of amphibians with internalized gills. Unlike amphibians with internalized gills which typically rely on the changing of pressures within the buccal and pharyngeal cavities to ensure diffusion of oxygen onto the gill curtain, neotenic salamanders such as Necturus use specified musculature, such as the levatores arcuum, to move external gills to keep the respiratory surfaces constantly in contact with new oxygenated water.

A dissected view of the levatores arcuum muscles in a Necturus maculosus specimen. These move the external gills, as a means of respiration.
In the Necturus, external gills begin to form as a means of combating hypoxia in the egg as egg yolk is converted into metabolically active tissue.

Molecular changes in the mudpuppy during post-embryonic development primarily due to the thyroid gland prevent the internalization of the external gills as seen in most salamanders that…
