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. [41] 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 ...
In peptide synthesis, TIPS is used as a scavenger for peptide groups being removed from the peptide sequence at the global deprotection. TIPS is able to scavenge carbocations formed in the deprotection of a peptide as it can act as a hydride donor in acidic conditions. [1] Silanes may be preferred as scavengers in place of sulfur-based scavengers.
A salamander (or deadman's foot or furnace bear) in the metallurgy dialect means all liquid and solidified materials in the hearth of a blast furnace below the tap hole. The target of the salamander tapping is to remove the remaining hot metal and slag from the blast furnace to allow a safe and efficient intermediate repair and blow-in of the ...
Desmognathus fuscus is a species of amphibian in the family Plethodontidae (lungless salamanders). [2] [3] The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form several distinct species, the southern dusky salamanders (D. auriculatus, D. valentinei).

Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.
Hydromantes, commonly referred to as web-toed salamanders, is a genus of the lungless salamander family, Plethodontidae; they achieve respiration through their skin and the tissues lining their mouth. They are endemic to mountains of California in the United States. [1]
Nototriton brodiei is a species of salamander in the family Plethodontidae. It is endemic to the Sierra del Merendón and known from its type locality, Sierra de Caral in Izabal Department, eastern Guatemala, and from the Cusuco National Park in northwestern Honduras. [1] [3] The specific name brodiei honors Edmund D. Brodie Jr., an American ...
The reason it is referred to as a big night is because there is a large number of salamanders moving at the same time. Warmer air and loose soil coupled with rain cause salamanders to leave their underground burrows. The event takes place at night to minimize predation. The rain on the big night keeps the salamanders skin from becoming dry. [1]
