Freeze branding is therefore seen as a permanent and low-impact means of tracking amphibians. [7] Freeze branding was tested on frogs that were released into the wild after branding and later recaptured. One set of researchers used a branding iron made from a length of copper wire, cooled in a dry ice ethanol bath for 30 minutes.
Human branding or stigmatizing is the process by which a mark, usually a symbol or ornamental pattern, is burned into the skin of a living person, with the intention of the resulting scar making it permanent. This is performed using a hot or very cold branding iron.
In stark contrast to traditional hot-iron branding, freeze branding uses an iron that has been chilled with a coolant such as dry ice or liquid nitrogen. Instead of burning a scar into the animal's skin, a freeze brand damages the pigment-producing hair cells, causing the animal's hair to grow back white within the branded area.
A white marking on the crest of a horse's neck was created by freeze branding, a form of marking for identification that is nearly painless. Freeze brand detail on shoulder of horse. In stark contrast to traditional hot-iron branding, freeze branding uses an iron that has been chilled with a coolant such as dry ice or liquid nitrogen. Instead ...

Researchers use variation on humpback whale flukes to identify and track the animals. Photo-identification is a technique used to identify and track individuals of a wild animal study population over time.
Scarification involves scratching, etching, burning/branding, or superficially cutting designs, pictures, or words into the skin as a permanent body modification or body art. The body modification can take roughly 6–12 months to heal.
Freezing behavior, also called the freeze response or being petrified, is a reaction to specific stimuli, most commonly observed in prey animals, including humans. [1] [2] When a prey animal has been caught and completely overcome by the predator, it may respond by "freezing up/petrification" or in other words by uncontrollably becoming rigid or limp.
